Title: Non-constant positive steady state of a ratio-dependent predator-prey system
Abstract: In this paper,a ratio-dependent predator-prey system with Holling-Ⅲ functional response is considered.The locally asmptotic stability for the constant solution and the prior estimates of the positive steady state are discussed,and the conditions of non-existence of non-constant positive steady state are given.At the same time,the existence of non-constant positive steady state are studied mainly through the degree theorem.
