Fractional $p$-Laplacians via Neumann problems in unbounded metric measure spaces

Luca Capogna, Ryan Gibara, Riikka Korte +1

We prove well-posedness, Harnack inequality and sharp regularity of solutions to a fractional $p$-Laplace non-homogeneous equation $(-{\Delta }_p{)}^{s}u=f$, with $0<s<1$, $1<p<\infty$, for d…
