Abstract:
This article concerns the effect of slow diffusion in
two-species competition-diffusion problem with
spatially homogeneous nearly identical reaction terms.
In this case all (nonnegative) equilibria are spatially homogeneous,
and the set of nontrivial equilibria is the graph of a
-curve.
This article shows convergence of positive solutions to an equilibria
which is determined by the initial data. The proof relies on the existence
of a Lyapunov function and is adapted from [6] which dealt with linear
diffusion.
