Paper Title
Existence Of Positive Solutions For A (P, Q) _Laplacian Nonlinear System

In this paper, I study some (p, q) laplacian differential systems with boundary value conditions on a bounded domain. My technic is based on the fixed point theorems in cones. By using the fixed point theorems, I provide suficient conditions under which the above system has positive solution. I establish some propositions and I prove the existence of positive solutions for this equations. AMS Subject Classifications: 34B15, 34B20, 35J20, 35J60.
