Gregor Pasemann (HU)
We consider the problem of estimating the diffusivity of a stochastic heat equation (or more generally, the parametrized drift of an abstract linear stochastic parabolic evolution equation) from...

Abstract:
What do high dimensional convex bodies look like? How does the spectrum of a random matrix behave as its dimension grows? How does the connectivity of a graph evolve as its size grows? In...

The sandpile model (aka chip-firing game) is a toy model for studying self-organized criticality (SOC). SOC models are characterized by displaying power-law probability behaviour of certain quantities...
mehr erfahrenDr. Christian Rose (Potsdam)
Abstract: On Riemannian manifolds the conjunction of Gaussian upper heat kernel bounds and the volume doubling property of balls are equivalent to Sobolev inequalities in arbitrarily small balls. The...

I'll give a concise introduction to jet bundles of vector bundles. They allow to treat (higher) derivatives of sections in a coordinate invariant way without the need to introduce connections....
mehr erfahrenFernando Lledo (University Carlos III de Madrid)
In the present talk I will briefly review certain aspects of the dichotomy amenable/paradoxical in the category of metric spaces and inverse semigroups. Then I will address the question of defining a...

Abstract: SMPs offer a way of dividing a given object (domain, manifold or graph) into a given number of pieces in an ``analytically optimal'' way: typically, one attempts to minimise an energy...

Connections on Fréchet vector bundles and Fréchet Lie groups. [I.4.5-I.4.6]

I will discuss some recents applications and developments surrounding the Ornstein-Weiss Rokhlin lemma involving quantitative versions of orbit equivalence and questions of tileability in topological...

This is a co-organized colloquium with the CRC 1294 Data Assimilation
Scientific visualization is classically defined as the process of graphically displaying scientific data. However, this process is...

Abstract:
Eigenvalue interlacing is a tremendously useful tool in linear algebra
and spectral analysis. In its simplest form, the interlacing
inequality states that a rank-one positive perturbation...

In this talk we will introduce a definition of 'research data' in mathematics which encompasses all digital objects you handle in the process of doing research. We will discuss how these data can be...

Results from a few years ago of Kennedy and Schafhauser characterize simplicity of reduced crossed products AxG, where A is a unital C*-algebra and G is a discrete group, under an assumption which...
