Abstract
In this paper, we study the concentration phenomenon of a positive ground state solution of a nonlinear Schrodinger equation on RN. The coefficient of the nonlinearity of the equation changes sign. We prove that the solution has a maximum point at x(0) is an element of Omega(+) = {x is an element of R-N : Q( x) > 0} where the energy attains its minimum. (C) 2010 Elsevier Ltd.
