Regularity for solutions of nonlocal, nonsymmetric equations
Annales de l'I.H.P. Analyse non linéaire, Volume 29 (2012) no. 6, p. 833-859
We study the regularity for solutions of fully nonlinear integro differential equations with respect to nonsymmetric kernels. More precisely, we assume that our operator is elliptic with respect to a family of integro differential linear operators where the symmetric parts of the kernels have a fixed homogeneity σ and the skew symmetric parts have strictly smaller homogeneity τ. We prove a weak ABP estimate and C 1,α regularity. Our estimates remain uniform as we take σ2 and τ1 so that this extends the regularity theory for elliptic differential equations with dependence on the gradient.
