Harnack inequality for Nonlocal operators on Manifolds with nonnegative curvature
arXiv:2101.06903 · doi:10.1007/s00526-021-02124-0
Abstract
We establish the Krylov Safonov Harnack inequalities and Holder estimates for fully nonlinear nonlocal operators of non-divergence form on Riemannian manifolds with nonnegative sectional curvatures. To this end, we first define the nonlocal Pucci operators on manifolds that give rise to the concept of non-divergence form operators. We then provide the uniform regularity results for these operators which recover the classical results for second order local operators as limits.
