In this paper, we study the following fractional Schrödinger equations
where
s∈(0,1),
N>2s,
(−Δ)s stands for the fractional Laplacian. Under more relaxed assumption on
f(x,u), we obtain a new existence result of infinitely many high energy solutions via Symmetric
Mountain Pass Theorem, which unifies and improves Theorem 1.2. in Teng (2015).
