Three solutions for a class of nonlinear systems involving the (𝒑, 𝒒) _Laplacian Problems

In this paper, I study the existence of positive solutions for a class of nonlinear elliptic systems of (p,q)-Laplacian system. I provide suitable conditions under which, the problem has three positive solutions.
