Infinitely many solutions for fractional Schrödinger equation with potential vanishing at infinity

Abstract: The paper investigates the following fractional Schrödinger equation: (-) s u + V(x)u = K(x)f (u), x ∈ R N , where 0 < s < 1, 2s < N, (-) s is the fractional Laplacian operator of order s. V(x), K(x) are nonnegative continuous functions and f (x) is a continuous function satisfying some conditions. The existence of infinitely many solutions for the above equation is presented by using a variant fountain theorem, which improves the related conclusions on this topic. The interesting result of this paper is the p… Show more

“…Recently, the fractional Schödinger equation has became a fundamental equation in fractional quantum mechanics, where, when ε → 0 is taken in (1.2), the existence of solutions is very important; see [14] and the references therein. In the past few years, many works were devoted to establishing the existence and multiplicity of solutions of fractional Schödinger equation, see [15][16][17][18][19][20][21][22] and the references therein. Recently, the existence of solutions of fractional Schödinger equation with perturbation was investigated, see [18][19][20][21].…”

“…1 Recently, fractional Schrödinger equation has been become a fundamental equation in fractional quantum mechanical when studying the particles on stochastic fields modeled. Therefore, research on nonlinear Schrödinger equation involving fractional Laplacian operator attracts a great deal of attention and interest, please see previous studies [5][6][7][8][9][10][11][12][13][14][15][16] and so on. In Equation (1.1), let = 1, Equation (1.1) translate to the following classical Schrödinger equation:…”
