On a Class of Elliptic Equations for the N-Laplacian in R^n with One-Sided Exponential Growth

Abstract

2000 Mathematics Subject Classification: 35J40, 49J52, 49J40, 46E30By means of a suitable nonsmooth critical point theory for lower semicontinuous functionals we prove the existence of infinitely many solutions for a class of quasilinear Dirichlet problems with symmetric non-linearities having a one-sided growth condition of exponential type.The research of the authors was partially supported by the MIUR project “Variational and topological methods in the study of nonlinear phenomena” (COFIN 2001). The second author was also supported by the Istituto Nazionale di Alta Matematica “F.Severi” (INdAM
