Events for 28 October 2020

Francisco Silva: On the Asymptotic Nature of First Order Mean Field Games

12:00pm, zoom

In this talk we consider a class of finite horizon first order mean field games. The main focus here will be to provide a simple proof of convergence of symmetric N-player Nash equilibria in distributed open-loop strategies to solutions of the mean field game in Lagrangian form. The talk is based on a joint work with Markus Fischer (University of Padua).

Angelika Manhart: Aggregation without attraction: Analysing collective dynamics of swimmers and tethered obstacles.

1:00pm, https://durhamuniversity.zoom.us/j/92025466169?pwd=ZnI3ZHVqejlQQU4wQVNSeTgzcmZhUT09

Aggregation phenomena in biology and beyond are often attributed to attraction between individuals. In this work we study how elastically tethered obstacles interacting with the swimmers impact the macroscopically created patterns. Simulations of an individual-based model reveal at least three distinct large-scale patterns: travelling bands, trails and moving clusters. This motivates the derivation of a macroscopic partial differential equations model, for which we assume large tether stiffness. The result is a coupled system of non-linear, non-local partial differential equations. We use linear stability analysis to predict pattern size from model parameters. Further analysis of the macroscopic equations reveal that, surprisingly, the obstacle interactions induce short-ranged swimmer aggregation, irrespective of whether obstacles and swimmers are attractive or repulsive.
