| Abstract: | This paper is concerned with a class of third order difference systems with Dirichlet boundary condition.By virtue of the corresponding property of Green function and using Leggett-Williams fixed point theorem,the existence of three positive solutions of this systems are obtained under the assumption that the nonlinear term satisfies some suitable conditions. |
