Abstract:

Using mixed monotone fixed point theorem in the cone theory, we studied Dirichlet boundary value problems of nonlinear elliptic  systems with singularity, obtaining the existence and the uniqueness of positive solutions for nonlinear elliptic systems, under conditions of the nonlinear terms being mixed monotone.

Key words: Dirichlet boundary value problem, elliptic systems, positive solutions, existence, uniqueness
