题目:The Fisher-KPP equation over graphs: An application to species spreading in river networks

Abstract : In this talk, we consider the dynamical behavior of a new species spreading from a location in a river network where two or three branches meet, based on the widely used Fisher-KPP advection-di usion equation. The river branches are represented by some simple graphs with every edge a half in nite line,meeting at a single vertex. We obtain a rather complete description of the long-time behavior for every case under consideration, which can be loosely described by a trichotomy, including two different kinds of persistence states as parameters vary. The talk is based on joint work with Bendong Lou, Rui Peng and Maolin Zhou.
