Oberseminar p-adische Arithmetik: Geometric Representation Theory: Arghya Sadhukhan: Blocks, duality and projective objects

Gijs Heuts (Utrecht University): A Beilinson fiber square for telescopically localized K-theory

Abstract: I will report on ongoing joint work with Devalapurkar and Schlank. We construct a telescopic analog of the Beilinson fiber square, providing a simple ...

Zahra Mohammadi (Uni Münster): On the model theory of the free factor complex and its connection to free groups

Abstract: The free factor complexes (\mathrm{AF}_n) and (\mathrm{OF}_n) are built from the nontrivial proper free factors of (F_n) and their conjugacy classe...

Oberseminar Differentialgeometrie: Grigory Solomadin (Marburg), Vortrag: Generators and relations for equivariant cohomology of GKM manifolds

Abstract. Interesting invariants of manifolds with compact, effective, smooth torus actions (with nonempty and finite fixed points) are recorded in the respecti...

Mittagsseminar zur Arithmetik: Yifrei Zhao: Depth-0 supercuspidal L-packets of tame covers

We generalize the DeBacker--Reeder/Kaletha construction of depth-0 supercuspidal L-packets to all tame covers defined by étale cohomology. This can be seen as t...

Lamberto Tresoldi (Ecole Polytechnique Paris): Nonlinear stability of Schwarzschild black holes for the Einstein-massless Dirac system in spherical symmetry

We will discuss the nonlinear stability of Schwarzschild black holes for the Einstein?massless Dirac system under spherical symmetry. In particular, we will exp...

Johannes Christensen (Aarhus): Tracial weights on crossed product C*-algebras by abelian groups. Oberseminar C*-Algebren.

In this talk, I will discuss ongoing work with R. Neagu and G. Szabó concerning weights on crossed product C*-algebras arising from actions of locally compact a...
