Abstract:
In this article we study the fractional Schr\"odinger equations
where
,
,
stands for the
fractional Laplacian of order
.
First by using Morse theory in
combination with local linking arguments, we prove the existence of at least
two nontrivial solutions. Next we prove that the problem has k distinct
pairs of solutions by using the Clark theorem.
