This paper is devoted to the study of existence and multiplicity of solutions for a multiparameter quasilinear Schrödinger problem whose hypotheses allows us to consider semipositone and critical concave convex problems. The approach is based by combining explicitely constructions of sub-supersolutions and variational methods.
