 Conference: Nearby Cycles and Derived Geometry (Feb 26 - Mar 1 2024)

Aim and Scope

The geometry of nearby cycles, using microlocal methods or motivic approaches, has recently seen spectacular advances in many different directions: symplectic geometry, non-archimedean analytic geometry, or arithmetic geometry, using more and more tools from derived algebraic geometry and higher category theory. This has many applications in mirror symmetry, in the Langlands program, or in ramification theory, for instance. This conference aims at gathering experts from different fields to emulate progress in different branches of geometry.

Practical Information


City of Regensburg: Regensburg is a Unesco World Heritage site that is famous for its well-preserved medieval city center and its beautiful Gothic cathedral.
Further information about Regensburg can be found here.

Internet: Access to eduroam and BayernWLAN is available throughout the Mathematics Building.

Accomodation: Regensburg is a tourist destination and we encourage guests to book their rooms as early as possible. Here is a list of hotels in the area:

- Hotel Münchner Hof (In the city center, one must take a bus to the University.)

- Hotel Kaiserhof am Dom (In the city center, one must take a bus to the University.)

- Hotel Jakob (In the city center, one must take a bus to the University.)

- Hotel Apollo (Near the University, but limited eating options nearby.)

- Hotel Wiendl (Between the city center and the University.)

- Hotel Central (Between the city center and the University, one must take a bus to the University.)

Family Friendly Campus: Our UR family service offers various rooms for families and services. If you need further information look here.


All lectures and research talks are in the lecture hall M311, at the 3rd floor of the Mathematics building of Regensburg University (Attention: not the department "Mathematik und Informatik" of the OTH).

One can reach the University of Regensburg by following the instructions here and see here for maps of the campus. Many of the participants will probably arrive by bus at the Central Bus Station of the university which is close to the math building, a bit more towards North (=top of the plan).

Inside of the Mathematics building, use the staircase next to the main entrance and go up to the top.

Programm and Schedule

The schedule of the conference will follow a month before the conference.


Pre-Registration: There is a limited capacity of 65 attendees. Kindly register in advance through the provided Google form.
