Games on Heterogeneous Graphs


A major challenge in evolutionary biology is to understand how spatial
population structure affects the evolution of social behaviors such as
cooperation. This question can be investigated mathematically by
studying evolutionary processes on graphs. Individuals occupy
vertices and interact with neighbors according to a matrix game.
Births and deaths occur stochastically according to an update rule.
Previously, full mathematical results have only been obtained for
graphs with strong symmetry properties. Our group is working to
extend these results to certain classes of asymmetric graphs, using
tools such as random walk theory and harmonic analysis.
