### Multiple solutions of critical singular degenerate elliptic system with concave-convex nonlinearities

#### Abstract

This paper is devoted to study a class of critical singular degenerate elliptic system with concave-convex nonlinearities and sign-changing weight functions. The existence and multiplicity of nontrivial nonnegative solutions are obtained by the variational.
