On the regularity theory for mixed local and nonlocal quasilinear elliptic equations

P Garain, J Kinnunen - Transactions of the American Mathematical Society, 2022 - ams.org
We consider a combination of local and nonlocal $ p $-Laplace equations and discuss
several regularity properties of weak solutions. More precisely, we establish local …

Fractional thoughts

N Garofalo - arxiv preprint arxiv:1712.03347, 2017 - arxiv.org
In this note we present some of the most basic aspects of the fractional Laplacean with a self-
contained and purely didactic intent, and with a somewhat different slant from the several …

Higher Hölder regularity for mixed local and nonlocal degenerate elliptic equations

P Garain, E Lindgren - Calculus of Variations and Partial Differential …, 2023 - Springer
We consider equations involving a combination of local and nonlocal degenerate p-Laplace
operators. The main contribution of the paper is almost Lipschitz regularity for the …
