Neumann conditions for the higher order $s$-fractional Laplacian $(-\Delta {)}^{s}u$ with $s>1$

B. Barrios, L. Montoro, I. Peral +1

In this paper we study a variational Neumann problem for the higher order $s$-fractional Laplacian, with $s>1$. In the process, we introduce some non-local Neumann boundary conditi…
