Title: Diffusion processes on rough spaces and random geometric models
Abstract: Mathematical models in physics, biology, engineering, material sciences and social media are usually developed to understand structures and phenomena of high complexity. The more realistic a model is, the more “roughness” we expect to find. Introducing randomness allows us to treat richer, more complicated situations. In this talk I will outline how my research in analysis and probability aims to gain a better understanding of these structures: On the one hand, studying stochastic processes intrinsic to a certain space can also reveal geometric and analytic information about it. On the other hand, the geometric properties of random sets and the asymptotic behavior of associated functionals are key in the development of statistical tools to analyze spatial data.

Title: Algebraic funtf Completion

Abstract: In this talk we will define the finite unit norm tight frame (funtf) variety. The algebraic funtf completion problem is the determination the fiber of a projection of this funtf variety onto a set of coordinates. We will give a characterization of the bases of the algebraic matroid underlying the funtf variety in R^3 and give our partial results for higher dimension.
