#### Prof. Dr. Benjamin Gess (Universität Bielefeld, MIS Leipzig): Path-by-path regularization by noise for scalar conservation laws

In this talk we will revisit regularizing effects of noise for nonlinear SPDE. In this regard we are interested in phenomena where the inclusion of stochastic p...

#### Oberseminar Algebra und Geometrie: Thomas Goller: Cobordism formulas for finite Quot schemes

I want to explain a connection between two topics in algebraic geometry: (a) Moduli problems: parametrizing quotients of a vector bundle (Quot scheme). (b) St...

#### Oberseminar Algebra und Geometrie: Leonardo Mihalcea (Virginia Tech University): Chern classes of Schubert cells, stable envelopes, and positivity

The Chern-Schwartz-MacPherson (CSM) class of a compact (complex) variety X is a homology class which provides an analogue of the total Chern class of the tange...

#### Albert Sheu (University of Kansas): Line Bundles over Multipullback Quantum Complex Projective Spaces. Oberseminar C*-Algebren

Among the popular and well analyzed quantum spaces $X_{q}$ with their $K$-groups \$K^{i}\left( X_{q}\right) \equiv K_{i}\left( C\left( X_{q}\right) \right)...

#### Oberseminar Differentialgeometrie: Mauricio Bustamante, Augsburg, Vortrag: Bundles with fiberwise negatively curved metrics

A smooth M-bundle is said to be negatively curved if its fibers are equipped with Riemannian metrics of negative sectional curvature, varying continuously from...
