13. október, 11:40 í N-130. Fyrirlesari: Brigitte Servatius (Worcester Polytechnic Institute) Titill: Random regular graphs and their rigidity properties in the plane. Ágrip: We start with some elementary examples of random regular graphs and an algorithm to generate them. We explain how graph theoretic properties such as regularity, planarity, and transitivity influence planar rigidity and

October 6, 11:40 Room N-130 Speaker: Ejnar Bjarki Gunnarsson (University of Iceland) Title: The site frequency spectrum of a neutrally evolving tumor Abstract: The site frequency spectrum (SFS) is a popular summary statistic of genomic data, recording the frequencies of mutations within a given population. While the SFS of a constant-sized population undergoing neutral mutations

September 29, 11:40 Room N-130 Speaker: Alexander Rashkovskii (University of Stavanger, Norway) Title: Pluricomplex Green functions Abstract: The standard notion of Green’s functions for linear differential operators cannot be used directly in multidimensional complex analysis. Instead, several different concepts were introduced by choosing specific fundamental solutions of the (highly non-linear) complex Monge-Ampère equation. I will

September 22, 11:40 Room N-130 Speaker: Herman Servatius (Worcester Polytechnic Institute) Title: Rigidity and movability of configurations in the projective plane. Abstract: Configurations of points and lines in the plane have a long history. The Theorem of Pappus from the fourth century begins a classical theory that has been advanced by Desargues, Pascal, Cayley, Steinitz,
