Interior and boundary regularity results for strongly nonhomogeneous $p,q$-fractional problems

Jacques Giacomoni, Deepak Kumar, K. Sreenadh

In this article, we deal with the global regularity of weak solutions to a class of problems involving the fractional $(p,q)$-Laplacian, denoted by $(-\Delta {)}_p^{s_1}+(-\Delta {)}_q^{s_2}$,…
