Besov regularity of solutions to the Dirichlet problem for the Bessel $(p,s)$-Laplacian

Juan Pablo Borthagaray, Leandro M. Del Pezzo, José Camilo Rueda Niño

We study the Dirichlet problem for a class of fractional $p$-Laplacian operators of order $s\in (0,1)$ defined through the Riesz fractional gradient, which differs fundamentally f…
