WEAK SOLUTIONS FOR A CLASS OF KIRCHHOFF TYPE EQUATIONS WITH NONLINEAR NEUMANN BOUNDARYCONDITIONS VIA VARIATIONAL METHODS

This paper deal with the class of Kirchho type problem withnonlinear Neumann boundary conditions. Using (S+) mapping theory andthe variational method, some result on existence and multiplicity for theproblem are obtained.
