Evolutionary branching is sympatric speciation driven by competition
between dominant species and their mutants. The traditional approach to
study evolutionary branching is to use pairwise-invasibility plot
(PIP). However, PIP is only suitable for the branching of a single
species with a single trait. With multiple co-evolving traits or
species, this method breaks down because the evolution/branching in one
trait changes the PIP of other traits. In this talk, I introduce a
dynamical method to study the branching of multiple co-evolving traits
and species, and give the branching conditions.
