Infinitely many solutions for the Dirichlet problem involving the   p-Laplacian in annulus
  We present a result of existence of infinitely many solutions for the Dirichlet problem involving the p-Laplacian in annular domains, when $p\leq N$, contouring the failure of compactness of $W^{1,p}(\Omega)$ in $C^0(\bar{\Omega})$ applying a variable change.
