Abstract: This paper is concerned with a class of fractional Schrödinger equation with Hardy potential (−Δ)su+V(x)u−κ|x|2su=f(x,u),x∈RN, where s∈(0,1) and κ⩾0 is a parameter. Under some suitable conditions on the potential V and the nonlinearity f, we prove the existence of ground state solutions when the parameter κ lies in a given range by using the non-Nehari manifold method. Moreover, we investigate the continuous dependence of ground state energy about κ. Finally, we are able to explore the asymptotic behavior of ground state solutions when κ tends to 0.
