## Abstract We prove that bounded harmonic functions of anisotropic fractional Laplacians are HΓΆlder continuous under mild regularity assumptions on the corresponding LΓ©vy measure. Under some stronger assumptions the Green function, Poisson kernel and the harmonic functions are even differentiable

A growth lemma for certain discrete symmetric Laplacians defined on a lattice Z d Ξ΄ = Ξ΄Z d βŠ‚ R d with spacing Ξ΄ is proved. The lemma implies a De Giorgi theorem, that the harmonic functions for these Laplacians are equi-HΓΆlder continuous, Ξ΄ β†’ 0. These results are then applied to establish regularity
