Periodic solutions for the one-dimensional fractional Laplacian

B. Barrios, J. García-Melián, A. Quaas

In this paper we are concerned with the construction of periodic solutions of the nonlocal problem $(-\Delta {)}^{s}u=f(u)$ in $\mathbb{R}$, where $(-\Delta {)}^s$ stands for the $s$-Laplacian, $s…
