Title: Exact asymptotic analysis for spatially extended stochastic
population dynamics.
Speaker: Stephen Cornell, reader in mathematical ecology at the
University of Leeds, UK. I have a background in nonequilibrium
statistical physics, but for the past 10 years I have been working in
theoretical ecology. I am particularly interested in methods for
calculating the properties of populations that interact spatially. This
talk will focus on a perturbative technique that I have been developing
with Otso Ovaskainen, where the length scale of interactions is assumed
sufficiently large (relative to the distance between neighbours) that
the dynamics is `close' to mean-field.
