Title: Blow up method for existence and non-existence of radial solutions for systems of quasilinear equations with weight, a revision.
Abstract: In this talk we will deal with with existence of positive radial solutions for a systems of quasilinear elliptic equations with weights in a ball, via blow up. Thus from some results for nonexistence of solutions in R^N (ground states) one gets a-priori
bounds of solutions , then existence of solutions follows from topological degree arguments.
