Andreatta and A. Vezzani) We introduce a definition of relative Hyodo-Kato cohomology for rigid analytic varieties, based on the relative motivic nearby cycle functor, and a corresponding theory of coefficients. We prove a Hyodo-Katoisomorphism with de Rham cohomology, provide an explicit description of the &quot;constructible&quot; objects, and compare this definition to relative log-rigid cohomology. <br /> <br /> '''Shachar Carmeli - Steenrod Operations in Syntomic Cohomology and Duality for Brauer Groups in Characteristic 2'''<br /> The Brauer group of a surface over a finite field of characteristic p carries a canonical skew-symmetric pairing, constructed by Artin, Tate, and Milne. Tate conjectured that this pairing is in fact alternating. I will discuss a joint work with Tony Feng addressing this conjecture for surfaces in characteristic 2. The case of odd primes was previously settled by Feng using Steenrod operations on mod 2 étale cohomology. <br /> Our extension of Feng's approach to the characteristic 2 case relies on the construction and analysis of Steenrod operations in syntomic cohomology, building on Voevodsky's motivic Steenrod algebra and Lurie's theory of spectral prismatization.<br /> <br /> '''Dustin Clausen - Refining Weil groups'''<br /> In number theory, the absolute Galois group of Q gets refined to the Weil group of Q, a locally compact group whose profinite completion recovers the Galois group. I will explain that this process can and should be continued, by carefully adding higher homotopy groups to get an object (formally, a condensed anima) which, from various perspectives, is better-behaved than both the Weil group and the absolute Galois group.<br /> <br /> '''Hélène Esnault - On the restriction map in ''p''-adically complete de Rham or prismatic cohomology (joint work with Mark Kisin and Alexander Petrov):'''<br /> For $X$ smooth proper over ${\mathbb Z}_p$ and $U $ a smooth affine, we show that the restriction homomorphism $H_{prism}^i(X) \to H^i_{prism}(U)^{sep}$ in the separated quotient of prismatic cohomology $H^i_{prism}(U)$ dies if $H^0(X mod p, \Omega^i)=0$, likewise for $p$-adically complete de Rham cohomology: under the same assumption the restriction homomorphism $H^i_{dR}^i( \hat X) \to H^i_{dR( \hat U)^{sep}$ in the separated quotient of $p$-adically complete de Rham cohomology $H^i_{prism}(U)$ dies. Daniel Caro and Marco D’Addezio lifted the vanishing of $H^i_{dR}^i( \hat X) \to H^i_{dR}( \hat U)^{sep}$ to the vanishing of $H^i_{dR}^i( \hat X) \to H^i_{dR}( \hat U)$ under the extra assumption $H^1(X, \Omega^{i-1})=0$. Indeed, their theorem can in turn be lifted to prismatic cohomology, so far modulo torsion: under the extra assumption $H^1(X, \Omega^{i-1})=0$, the restriction$H _{prism}^i(X) \to H^i_{prism}(U)_{m}$ dies, where $m$ is the maximal ideal of the prism. On the other hand. the algebra structure on prismatic, resp. $p$-adically complete de Rham cohomology kills the square of the non-separated part. On the de Rham side this can be deduced from a more precise formulation of the theorem ofCaro-D’Addezio mentioned above. <br /> <br /> <br /> '''Fabian Hebestreit - On the Weiss-Williams index<br /> (based on work in progress with A.Bianchi, K.Hilman, D.Kirstein, C.Kremer, M.Land, T.Nikolaus, W.Steimle):'''<br /> I will explain a construction of the Weiss-Williams index classes for manifold bundles in the language of Poincaré categories. The particular view this affords allows one to coalesce these classes into a topological field theory with values in cobordism categories of self-dual parametrised spectra. The underlying homotopy types of these categories are Weiss-Williams' LA-spectra, originally custom made as the home for their indices. This observation on the one hand refines and unifies their work with separate constructions of Bökstedt and Madsen (with target Waldhausen's A-spectra) and Basterra, Bobkova, Ponto, Tillmann and Yaekel (with target hermitian K-spectra of the integers) and on the other provides a simple proof of the Weiss-Williams index theorem and a fresh perspective on their map connecting block homeomorphisms and Whitehead spectra.<br /> <br /> '''Manuel Krannich - Pontryagin–Weiss classes'''<br /> Pontryagin classes were originally considered as invariants of real vector bundles, but it was realised in the 60s that they can be defined more generally for Euclidean bundles, that is, fibre bundles whose fibres are homeomorphic to Euclidean space. Thisled to the question whether the well-known vanishing of large-degree Pontryagin classes for small-dimensional vector bundles continues to hold in the setting of Euclidean bundles. Surprisingly, Weiss proved a few years ago that this often fails. I will explaina strengthening of his result resulting from joint work with A. Kupers: For every k&gt;0, there exists a 6-dimensional Euclidean fibre bundle over a sphere whose kth Pontryagin class is nontrivial.<br /> <br /> '''Hokuto Konno - Family gauge theory and diffeomorphism groups:'''<br /> One of the major advances in topology over the past decade has concerned diffeomorphism groups of higher-dimensional manifolds. On the other hand, it has long been known that dimension 4 is special in the classification of manifolds. Such special phenomena are detected using gauge theory. Recent advances in gauge theory for families have revealed that similar phenomena in dimension 4 also appear in diffeomorphism groups, in striking contrast with results in higher dimensions. In this talk, I will survey these new phenomena in dimension 4.<br /> <br /> '''Akhil Mathew - Sheared Witt vectors (after V. Drinfeld, E. Lau, and T. Zink):'''<br /> Motivated by Dieudonné theory, V. Drinfeld and E. Lau introduced a &quot;decompletion&quot; of the ring of Witt vectors W(R) of a derived p-complete ring R such that (R/p)_{red} is perfect, extending a construction of T. Zink. I will explain various characterizations of this decompletion (called the sheared Witt vectors) and some examples. (Joint work in progress with Bhargav Bhatt, Vadim Vologodsky, and Mingjia Zhang.)<br /> <br /> '''Thomas Nikolaus -Delta-Rings in Arithmetic and homotopy theory'''<br /> This talk will be about different instances and applications of the concept of a delta rings (and Witt vectors) in arithmetic andhomotopy theory. In particular we will analyse how generalizations control E_\infty-rings and state some conjectures and results along these lines. If time permits we will also introduce the dual notion and report on recent progress on coalgebras.<br /> <br /> '''Viktoriya Ozornova - What is an (∞,∞)-category?'''<br /> In this talk, we will address the abstract frameworks for inductive and coinductive notions of (∞,∞)-categories. We will examine also the strict case as a blueprint for the actual study, as well as some of the differences between the strict and the weak case. This is joint work in progress with Martina Rovelli.<br /> <br /> '''Maxime Ramzi - K(1)-local K-theory of Azumaya algebras'''<br /> The determinant map provides a way to recover a line bundle from its K-theory class. In this talk, I will discuss a categorified variant of this fact, in an attempt to answer a question of the form : how much of an Azumaya algebra can one recoverfrom its K-theory ? In particular, I will explain how for fields, the p-power torsion Brauer group decategorifies exactly as a p-power torsion strict Picard group.<br /> <br /> '''Charanya Ravi - On the algebraic K-theory of Deligne-Mumford stacks'''<br /> For a finite group G, Artin's induction theorem states that the rational representation ring of G admits a decomposition in terms of representation rings of its cyclic subgroups. This gives an expression for the zeroth algebraic K-group of BG in terms of its cyclic subgroups. Inspired by this, the work of Vistoli gives such a decomposition of the algebraic K-group of coherent sheaves (or G-theory) of quotient stacks for finite group actions. We prove a similar induction theorem for the G-theory of all Deligne-Mumford stacks by looking at the automorphism groups at points of the stack. As an application, we see that the rational G-theory of a Deligne-Mumford stack coincides with the rational étale G-theory of its cyclotomic loop stack. This leads to an orbifold version of the Grothendieck-Riemann-Roch theorem. This is based on an ongoing joint work with Adeel Khan.<br /> <br /> '''Georg Tamme - Localizing invariants of pushouts and non-commutative Hodge theory'''<br /> Singular cohomology of a smooth, proper complex variety carries a pure Hodge structure consisting of a rational lattice given by singular cohomology with rational coefficients and a Hodge filtration on cohomology with complex coefficients coming from thecomparison with de Rham cohomology, these two structures interacting in a specific way. Katzarkov, Kontsevich, and Pantev conjecture that this should generalize to non-commutative smooth, proper varieties, i.e. to smooth, proper ℂ-linear stable ∞-categories.In this case, de Rham cohomology is replaced by periodic cyclic homology, and the rational lattice is conjecturally given by Toën’s and Blanc’s topological K-theory. As Deligne constructed a mixed Hodge structure on the singular cohomology of arbitrary complexvarieties, one may also ask what happens for not necessarily smooth or proper ℂ-linear stable ∞-categories. In this talk, I will indicate how results about localizing invariants on pushouts of rings can be used to prove some cases of the lattice conjecture,for example for certain group rings. Most of these results have also been obtained by different techniques by Konovalov. This is joint work with Markus Land.<br /> <br /> '''Peter Scholze'''<br /> <br /> '''Maria Yakerson - An alternative to spherical Witt vectors:'''<br /> Witt vectors of a ring form a “bridge” between characteristic p and mixed characteristic: for example, Witt vectors of a finite field F_p is the ring of p-adic integers Z_p. Spherical Witt vectors of a ring is a lift of classical Witt vectors to the world of higher algebra, much like sphere spectrum is a lift of the ring of integers.In this talk we will discuss a straightforward construction of spherical Witt vectors of a ring, in the case when the ring is a perfect F_p-algebra. Time permitting, we will further investigate the category of modules over spherical Witt vectors, and explain a universal property of spherical Witt vectors as an E_1-ring. This is joint work with Thomas Nikolaus.<br /> <br /> '''Inna Zakharevich - Towards a trace on the Grothendieck spectrum of varieties'''<br /> In this talk we discuss an alternate model of topological Hochschild homology. This model has the advantage that it is largely combinatorial, and thus exists independently of a choice of enrichment. The hope is that this model can lead to a meaningful trace andmodel of THH for the Grothendieck spectrum of varieties. This is joint work with Jonathan Campbell and Kate Ponto.<br /> <br /> ==Program and Schedule==<br /> <br /> {| class=&quot;wikitable&quot; style=&quot;text-align: center; cellpadding=&quot;10&quot;<br /> |-<br /> !

The representation theory of reductive symmetric spaces was extensively studied in the 1980s and 1990s by Erik van den Ban, Patrick Delorme, Henrik Schlichtkrull, and others, culminating in the Plancherel formula for the L2-space of G/H. This work generalizes the group case established by Harish-Chandra in the early 70s, where G = G' x G' and H is the diagonal subgroup.<br /> In our collaborative research with A. Afgoustidis, N. Higson, P. Hochs, and Y. Song, we are exploring this topic from the perspective of C*-algebras and K-theory. I will present these exciting new developments, highlighting novel aspects and differences from the traditional group case.</div> Buu10307

a semisimple abelian tensor category, equivalent to that of rational G-Mackey functors, which itself splits into a product of categories of rational representations of the Weil groups of subgroups of G. <br /> In this talk, I will explain how to generalize the algebraic splitting from the Burnside ring to any Green functor, and how this can be applied to equivariant KK-theory and to the homotopy category of suitable equivariant S-algebras.</div> Buu10307 https://sfb-higher-invariants.app.uni-regensburg.de/index.php?title=AG-Seminar_WS2021/22:&diff=2254 AG-Seminar WS2021/22:

Mathematically, they propose a geometric model of TMF, the spectrum of Topological Modular Forms, in terms of supersymmetric quantum field theories. My recent works have been motivated by their proposal. I explain my collaborations with Yuji Tachikawa relating the Anderson self-duality of topological modular forms (in homotopy theory) and absence of anomaly in heterotic string theory (in physics), and my recent collaboration with Theo Johnson-Freyd on understanding the geometric origin of the 576-periodicity of TMF. I would like to illustrate the exciting interplay between mathematics and physics.</div> Buu10307 https://sfb-higher-invariants.app.uni-regensburg.de/index.php?title=AG-Seminar_WS2021/22:&diff=1837 AG-Seminar WS2021/22: 2024-01-24T13:19:04Z <p>Buu10307: </p> <hr /> <div>'''AG Seminar''' <br /> <br /> '''Description:''' The aim of the Seminar is to present and discuss recent results in research areas from Homotopy Theory and K-theory to Global Analysis. <br /> <br /> '''Time and place:''' Thursday 12-14, SFB Lecture Hall.<br /> <br /> '''Zoom Link:''' https://uni-regensburg.zoom.us/j/7601042838?pwd=bUVEaHhuY01abmo4T3Fza1NZMEVNUT09<br /> <br /> <br /> <br /> <br /> '''Winter Semester 2023/24'''<br /> <br /> <br /> '''Schedule''' <br /> <br /> {|border=&quot;1&quot;<br /> !No<br /> !Date<br /> !Title / Abstract<br /> !Speaker<br /> |-<br /> |1<br /> |19.10.2023 <br /> |[[On the motivic Adams conjecture]]<br /> |Alexey Ananyevskiy<br /> |-<br /> |2<br /> |26.10.2023 <br /> |[[Dualizable categories and E-Theory]]<br /> |Benjamin Dünzinger/Ulrich Bunke<br /> |-<br /> |3<br /> |02.11.2023 <br /> |[[Dualizable categories and E-Theory-II]]<br /> |Benjamin Dünzinger/Ulrich Bunke<br /> |-<br /> |4<br /> |09.11.2023 <br /> |[[A pro-cdh topology and motivic cohomology of schemes]] <br /> |Shuji Saito<br /> |-<br /> |5<br /> |16.11.2023<br /> |Cohomological invariants of quadrics via Morava motives<br /> |Pavel Sechin <br /> |-<br /> |6<br /> |23.11.2023<br /> |Formal category theory within ∞-categorical proarrow equipments<br /> |Jaco Ruit<br /> |-<br /> |7<br /> |30.11.2023<br /> | <br /> | <br /> |-<br /> |8<br /> |07.12.2023<br /> |[[Motivic cohomology of mixed characteristic schemes]]<br /> |Tess Bouis<br /> |-<br /> |9<br /> |14.12.2023 <br /> |[[Six-functor formalisms are compactly supported]]<br /> |Josefien Kuijper<br /> |-<br /> |10<br /> |21.12.2023<br /> |Towards a pro-étale homotopy type of schemes<br /> | Sebastian wolf<br /> |-<br /> |11<br /> |11.01.2024<br /> |<br /> | <br /> |-<br /> |12<br /> |18.01.2024<br /> |Gabber's presentation lemma over a general base<br /> |Suraj Yadav <br /> |-<br /> |13<br /> |25.01.2024<br /> |[[Chow-Lefschetz motives]]<br /> |Bruno Kahn<br /> |-<br /> |14<br /> |01.02.2024<br /> |[[Topological Modular Forms and supersymmetric quantum field theories]]<br /> |Mayuko Yamashita <br /> |-<br /> |15<br /> |08.02.2024<br /> |tba<br /> |Georg Lehner (FU Berlin)<br /> |-<br /> |}<br /> <br /> <br /> <br /> &lt;hr&gt;&lt;hr&gt;<br /> <br /> <br /> <br /> <br /> <br /> '''Summer Semester 2023'''<br /> <br /> <br /> '''Schedule''' <br /> <br /> {|border=&quot;1&quot;<br /> !No<br /> !Date<br /> !Title / Abstract<br /> !Speaker<br /> |-<br /> |1<br /> |20.04.2023 <br /> | <br /> | <br /> |-<br /> |2<br /> |27.04.2023 '''12:30'''<br /> |Universality and Examples in the Context of Functorial Semi-Norms (PhD defense) <br /> |Johannes Witzig <br /> |-<br /> |3<br /> |04.05.2023 <br /> |No seminar <br /> | <br /> |-<br /> |4<br /> |11.05.2023 <br /> |tba<br /> |Hoang Kim Nguyen<br /> |-<br /> |5<br /> |18.05.2023<br /> |No seminar (holiday)<br /> | <br /> |-<br /> |6<br /> |25.05.2023<br /> |[[Separability in homotopical algebra]]<br /> |Maxime Ramzi (Copenhagen) <br /> |-<br /> |7<br /> |01.06.2023<br /> |[[Blow-ups and normal bundles in nonconnective derived geometry]] <br /> |Jeroen Hekking<br /> |-<br /> |8<br /> |08.06.2023<br /> |No seminar (holiday)<br /> |<br /> |-<br /> |9<br /> |15.06.2023 <br /> |The theorem of the heart<br /> |Giacomo Bertizzolo <br /> |-<br /> |10<br /> |22.06.2023<br /> |[[Shapes and locally constant sheaves]]<br /> | Marc Hoyois<br /> |-<br /> |11<br /> |29.06.2023<br /> |Norms and Transfers in Motivic Homotopy Theory<br /> |Brian Shin<br /> |-<br /> |12<br /> |06.07.2023<br /> |[[On the category of localizing motives]]<br /> |Alexander Efimov<br /> |-<br /> |13<br /> |13.07.2023<br /> |Twisted ambidexterity in equivariant homotopy theory<br /> |Bastiaan Cnossen<br /> |-<br /> |14<br /> |20.07.2023<br /> | (reserved)<br /> | <br /> |-<br /> |}<br /> <br /> <br /> &lt;hr&gt; &lt;hr&gt;<br /> <br /> <br /> '''Winter Semester 22/23'''<br /> <br /> <br /> '''Schedule''' <br /> <br /> {|border=&quot;1&quot;<br /> !No<br /> !Date<br /> !Title / Abstract<br /> !Speaker<br /> |-<br /> |1<br /> |20.10.2022 <br /> |Model categories for o-minimal geometry <br /> |Reid Barton (Univ.

A basic idea coming from the trace method for algebraic K-theory, is to modify the cdh-local motivic complex (defined as the cdh sheafication of the left Kan extension of the motivic complex for smooth schemes over a field) by using other complexes such as Hodge completed derived de Rham complexes and syntomic complexes.<br /> In this talk, we propose a different construction of a motivic complex using a new Grothendieck topology, pro-cdh topology, and sketch a proof of the comparison theorem of two motivic complexes for Noetherian schemes over a field.

If time permits, I will also mention how the basics of the classical theory of separable algebras extend to homotopical algebra.</div> Buu10307 https://sfb-higher-invariants.app.uni-regensburg.de/index.php?title=AG-Seminar_WS2021/22:&diff=792 AG-Seminar WS2021/22: 2023-05-18T17:25:07Z <p>Buu10307: </p> <hr /> <div>'''AG Seminar''' SummerSemester 23 <br /> <br /> <br /> '''Description:''' The aim of the Seminar is to present and discuss recent results in research areas from Homotopy Theory and K-theory to Global Analysis. <br /> <br /> <br /> '''Time and place:''' Thursday 12-14, SFB Lecture Hall.<br /> <br /> '''Zoom Link:''' https://uni-regensburg.zoom.us/j/7601042838?pwd=bUVEaHhuY01abmo4T3Fza1NZMEVNUT09<br /> <br /> &lt;hr&gt;<br /> <br /> '''Schedule''' <br /> <br /> {|border=&quot;1&quot;<br /> !No<br /> !Date<br /> !Title / Abstract<br /> !Speaker<br /> |-<br /> |1<br /> |20.04.2023 <br /> | <br /> | <br /> |-<br /> |2<br /> |27.04.2023 '''12:30'''<br /> |Universality and Examples in the Context of Functorial Semi-Norms (PhD defense) <br /> |Johannes Witzig <br /> |-<br /> |3<br /> |04.05.2023 <br /> | <br /> | <br /> |-<br /> |4<br /> |11.05.2023 <br /> | <br /> |Hoang Kim Nguyen<br /> |-<br /> |5<br /> |18.05.2023<br /> |holiday<br /> | <br /> |-<br /> |6<br /> |25.05.2023<br /> |[[Separability in homotopical algebra]]<br /> |Maxime Ramzi (Copenhagen) <br /> |-<br /> |7<br /> |01.06.2023<br /> |N.N. <br /> |Jeroen Hekking<br /> |-<br /> |8<br /> |08.06.2023<br /> |The Theorem of the Heart<br /> |Giacomo Bertizzolo<br /> |-<br /> |9<br /> |15.06.2023 <br /> | <br /> | <br /> |-<br /> |10<br /> |22.06.2023<br /> | <br /> | Marc Hoyois<br /> |-<br /> |11<br /> |29.06.2023<br /> |N.N<br /> |Ryomei Iwasa<br /> |-<br /> |12<br /> |06.07.2023<br /> |N.N<br /> |Alexander Efimov<br /> |-<br /> |13<br /> |13.07.2023<br /> |N.N<br /> |Bastiaan Cnossen<br /> |-<br /> |14<br /> |20.07.2023<br /> | (reserved)<br /> | <br /> |-<br /> |}<br /> <br /> <br /> &lt;hr&gt; &lt;hr&gt;&lt;br&gt;<br /> <br /> <br /> '''AG Seminar''' WinterSemester 22/23 <br /> <br /> <br /> '''Time and place:''' Thursday 12-14, SFB Lecture Hall.<br /> <br /> '''Zoom Link:''' https://uni-regensburg.zoom.us/j/7601042838?pwd=bUVEaHhuY01abmo4T3Fza1NZMEVNUT09<br /> <br /> &lt;hr&gt;<br /> <br /> '''Schedule''' <br /> <br /> {|border=&quot;1&quot;<br /> !No<br /> !Date<br /> !Title / Abstract<br /> !Speaker<br /> |-<br /> |1<br /> |20.10.2022 <br /> |Model categories for o-minimal geometry <br /> |Reid Barton (Univ.
