Abstract
- We study the following fractional Schrödinger equation where . Under some conditions on , we show that the problem has a family of solutions concentrating at any finite given local minima of provided that . All decay rates of are admissible. Especially, can be compactly supported. Different from the local case or the case of single-peak solutions, the nonlocal effect of the operator makes the peaks of the candidate solutions affect mutually, which causes more difficulties in finding solutions with multiple bumps. The methods in this paper are penalized technique and variational method. We study the following fractional Schrödinger equation \begin{equation*} \label{eq0.1} \varepsilon^{2s}(-\Delta)^s u + V(x)u = f(u), \,\,x\in\mathbb{R}^N, \end{equation*} where .
