"Multi-type logistic branching processes with selection: frequency process and genealogy for large carrying capacities"
Seminar "Interacting Random Systems" at WIAS Berlin, 11:30, WIAS-405-406
Abstract: We present a model for growth in a multi-species population. We consider two types evolving as a logistic branching process with mutation, where one of the types has a selective advantage. We first study the frequency of the disadvantageous type and show that, once the population approaches the carrying capacity, its evolution converges to a Gillespie-Wright-Fisher diffusion process. We then study the dynamics backward in time: we fix a time horizon at which the population is at carrying capacity and we study the ancestral relations of a sample of individuals. We prove that, provided that the advantageous and disadvantageous branching measures are ordered, this ancestral line process converges to the moment dual of the limiting diffusion. This talk is based on joint work with Julian Kern.

"Map enumeration and random noncommutative geometries"
Algebraic and Combinatorial Perspectives in the Mathematical Sciences via Zoom, 15:00
Abstract: In this talk I will discuss an approach to quantum gravity that constructs path integrals over spaces of finite dimensional spectral triples, called Dirac ensembles. Such integrals can be realized as bi-tracial multi-matrix integrals and can be studied via connections to map enumeration. Recent work has added matter fields to these models, and it has been shown that certain models can be rephrased as 3-colour problem and loop gas models.
