Abstract:
We prove the existence of solutions to the nonlinear
-periodic
problem
where the point
lies in the Dancer-Fucik spectrum, with
for some natural number m, and the nonlinearity
is bounded
with primitive,
,
satisfying a
Landesman-Lazer type condition introduced by Tomiczek in 2005.
We use variational methods based on the generalization of the
Saddle Point Theorem of Rabinowitz.
