Abstract:
This article is devoted to the study of multiple positive solutions
to a singular elliptic system where the nonlinearity involves a
combination of concave and convex terms. Using the effect of the
coefficient of the critical nonlinearity, and a variational
method, we establish the main result which is based on a compactness
argument.
