Abstract

We consider the semilinear Lane–Emden problem

where and is a smooth bounded domain of . The aim of the paper is to analyze the asymptotic behavior of sign changing solutions of (), as . Among other results we show, under some symmetry assumptions on , that the positive and negative parts of a family of symmetric solutions concentrate at the same point, as , and the limit profile looks like a tower of two bubbles given by a superposition of a regular and a singular solution of the Liouville problem in .
