摘要:
受对单个方程多解的存在性的研究的启发，本文研究具有非齐次边界条件的非线性椭圆方程组的存在性及多解性。由锥上Guo-Krasnoselskii不动点定理，本文证明了一类椭圆型方程组至少存在三个正解。Motivated by existence of solutions of single equation, in this paper we study the existence of mul-tiple solutions of a class of nonlienar elliptic systems with nonhomogeneous boundary conditions. Using Guo-Krasnoselski’s fixed point theorem on cones, we prove that there exist at least three positive solutions for this class of nonlinear elliptic systems.
