Abstract:

In this paper, by using subsuper solutions method, we study the existence of weak positive solutions for a new class of Laplacian nonlinear elliptic system in bounded domains, when , , and are sign-changing functions that maybe negative near the boundary, without assuming sign conditions on , and .
