An eigenvalue problem for non-bounded quasi-linear operator

Abstract

In this paper we study the eigenvalues associated with a positive eigenfunction of a quasilinear elliptic problem with a not necessarily bounded operator. For that, we use the bifurcation theory and obtain the existence of positive solution for a range of values of the bifurcation parameter.Dirección General de Enseñanza Superior (Ministerio de Educación y Ciencia)Ministerio de Ciencia y Tecnologi
