Abstract:This paper discusses the existence of a class of positive solutions for fourth-order elliptic system in space E×E=(H2(Ω)∩H0 1(Ω))×(H2(Ω)∩(H0 1(Ω))by using Leray-Schauder degree theory and strong maximum principle and constructing proper function instead of using coupling method and minimax theorem.
Keywords:fourth-order elliptic system  positive solutions  degree of Leray-Schauder
