Title: Coexistence and stability of solutions for a class of reaction-diffusion systems Author: Zhenbu Zhang (Jackson State Univ., MS, USA) Abstract: In this paper we consider the situation of two species of predators competing for one species of prey. We use comparison principles to study the global existence, the existence of non-trivial steady states and their stability. Submitted March 21, 2005. Published December 1, 2005.
