Spike-layered solutions of singularly perturbed quasilinear Dirichlet problems ✩

In this paper we study the existence and structure of a least-energy solution for a class of singularly perturbed quasilinear Dirichlet problems. Using the moving plane method we show that this leastenergy solution develops to a spike-layer solution on convex domains.  2003 Elsevier Inc. All rights reserved.
