Variatlonal methods and scalar nonlinearities

Pages 115-119 | Published online: 02 May 2007
 

Abstract

Different variational characterizations for critical values of potentials of scalar nonlinearities are given. On the one side the characterizations are direct generalizations of variational principles for eigenvalues of linear operators and on the other they derive from Ljuster-nik-Schnirelman-theory
