[MM Connect] Céline Berthaud, Adrian Celestino, Carlo Kaul, Jacopo Peroni, Frederic Weinheimer: MM Arrival Talks

Mittagsseminar zur Arithmetik: Alexandre Maksoud (MPIM Bonn): On the local geometry of the eigencurve near classical weight one points, and R=T theorems

The study of p-adic deformations of automorphic forms was initiated by Hida in the 1980s, following his discovery of systematic congruences between the Fourier ...

Paula Verdugo (MPIM Bonn): On the equivalence invariance of formal category theory. Oberseminar Topologie.

Equipments, a special kind of double categories, have shown to be a powerful environment to express formal category theory. We build a model structure on the ca...

Andrei Konovalov: Algebraic K-theory of singular hypersurfaces. Oberseminar Topologie.

Recent years have seen substantial progress in understanding algebraic K-theory of singular varieties. Still, computations of (higher) K-theory of singular vari...

Mittagsseminar zur Arithmetik: Claus Sorensen (San Diego): Derived variants of the Bernstein center mod p

The Bernstein decomposition makes precise how the category of smooth complex representations of a p-adic reductive group G is built from supercuspidals. The c...

Tea Seminar: Miguel Gentili (University of Muenster): The bounded cohomology of the transformation groups of Euclidean spaces

Bounded cohomology is a functional-analytic variant of ordinary cohomology with applications in the study of manifold geometry, rigidity theory, ergodic theory,...

Lucas Melo de Oliveira (Columbia University, New York): Extremal black hole formation from massive charged dust: sharpness of the mass-charge inequality

In forthcoming joint work with Christoph Kehle, we present a PDE-based proof that for any Einstein--Maxwell--matter system satisfying the local mass-charge ineq...

Tony Salvi (Institut de Mathématiques de Jussieu Sorbone Université, Paris): Semi-classical limit for Klein-Gordon equations

Quantum mechanics is well approximated by classical physics when Planck's constant is considered small, i.e., in the semi-classical limit. Typically, one can st...
