In this paper, we study the existence of sequence of small solutions for the following two classes of fractional Schrodinger equations (P) and (Pi): and where 0< s< 1,2s< N, f ∈ C(RN × R,R), V € C(RN,R), Q is a measurable function on RN, (-△)s is the fractional Laplacian operator. By variational method, two results are obtained. |
