We study the local regularity of solutions f to the integro-differential equation
$$ Af=g \quad \text{in } U $$for open sets \(U \subseteq \mathbb {R}^{d}\), where A is the infinitesimal generator of a Lévy process (Xt)t≥ 0. Under the assumption that the transition density of (Xt)t≥ 0 satisfies a certain gradient estimate, we establish interior Schauder estimates for both pointwise and weak solutions f. Our results apply for a wide class of Lévy generators, including generators of stable Lévy processes and subordinated Brownian motions.

我们研究积分微分方程 解f的局部正则性
$$ Af = g \ quad \ text {in} U $$为开集\(U \ subseteq \ mathbb {R} ^ {d} \) ,其中阿是Levy过程的无穷小发电机(X吨)吨≥0 。在假设(转变密度X吨)吨≥0满足一定的梯度估计,我们建立内部Schauder不估计两者逐点和弱解˚F。我们的结果适用于各种各样的Lévy发生器,包括稳定的Lévy过程和从属布朗运动的发生器。
