On sequences of large homoclinic solutions for a difference equation on the integers involving oscillatory nonlinearities
In this paper, we determine a concrete interval of positive parameters , for which we prove the existence of infinitely many homoclinic solutions for a discrete problem
where the nonlinear term has an appropriate oscillatory behavior at infinity, without any symmetry assumptions. The approach is based on critical point theory
Existence of solutions for p-Laplacian discrete equations
This work is devoted to the study of the existence of at least one (non-zero) solution to a problem involving the discrete p-Laplacian. As a special case, we derive an existence theorem for a second-order discrete problem, depending on a positive real parameter
