<div>Understanding the homotopy type of a space often benefits from studying its values under homology theories. Every homology theory determines a Bousfield localization on the category of spaces — for example, rational cohomology leads to rationalization, while $F_p$-homology induces $p$-completion. <br />
In favorable cases, these localizations admit explicit descriptions via monadic resolutions. <br />
A key example is the $p$-completion $L_p X$ of a nilpotent space $X$, which can be expressed as an inverse limit:<br />
$L_p X = lim_n (\Omega^\infty F_p \otimes \Sigma^\infty)^{n+1}(X)$.<br />
Similarly, any nilpotent space $X$ can be expressed as the inverse limit <br />
$X = lim_n (\Omega^\infty MU \otimes \Sigma^\infty)^{n+1}(X)$ of its iterated $MU$-homology, giving rise to the unstable Adams—Novikov spectral sequence.<br />
A fundamental ingredient in proving this equivalence is Bousfield and Kan's celebrated principal fibration lemma. <br />
<br />
In this talk, I will discuss how these ideas extend to oo-topoi and explain their application in motivic homotopy theory. In particular, I will sketch a proof of the principal fibration lemma in this broader context. <br />
This is joint work with Tom Bachmann and Anton Engelmann.</div>

<div>For X a compact oriented topological manifold and k a field, Verdier duality on locally constant sheaves of k-modules on X can be encoded in a non-commutative symplectic structure, called Calabi—Yau structure. Brav—Dyckerhoff also introduced a relative notion of such, which allows one to recover Verdier duality for manifolds with boundaries.<br />
If now X is equipped with a (nice enough) finite stratification P, we show that there exists a Calabi—Yau structure on the k-linear stable infinity-category of constructible sheaves on (X,P). In this case, even if X itself has no boundary, we will get a relative Calabi—Yau structure, where the role of the boundary is replaced by the tubular neighborhoods of the strata. This is joint work with Merlin Christ.</div>

<div>The stratified homotopy hypothesis proclaims an equivalence between a homotopy theory of stratified spaces, and the homotopy theory of such small (infinity,1)-categories in which every endomorphism is an isomorphism. In this talk, after an introduction into the homotopy theory of stratified spaces, I want to talk about an explicit presentation of this proclaimed equivalence in terms of a Quillen equivalence using Lurie’s construction of the infinity-category of exit-paths. Crucially, I will talk about a new semi-model structure on topological stratified spaces, which presents the aforementioned homotopy theory, and interacts particularly well with classical geometrical examples, such as Whitney stratified spaces – thus bridging the gap between the geometry and homotopy theory of stratified spaces.</div>
