Existence and stability of travelling wave solutions of competition models with migration effects. (English) Zbl 0751.92015
A two-species competition model with migration effects is considered, based on a semilinear hyperbolic system of partial differential equations. Travelling wave solutions are shown to exist, and the $$C^ 0$$-stability of these solutions is demonstrated. The asymptotic behaviour of some of these solutions is investigated.
A useful comparison theorem is established for a class of semilinear hyperbolic systems. Under certain conditions a solution which is initially “less” than another will remain so for all time.
