Solutions To Three Kinds Of Fractional Schr(?)dinger Equations

In this paper,we study the following three kinds of fractional Schrodinger equations with different potential:(?)and(?) and (?) where p ∈(1,2)in(1),p ∈(3+4s/3,3+2s/3-2s)in(3),V is different potentials,s ∈(3/4,1),β,λ,ω∈R are parameters,a and b are positive constants.We obtain the existence and multiplicity of solutions of the above three equations by variational methods especially fountain theorem.
