我们证明了分数 Sobolev 空间中具有可能不连续的 VMO 型系数的非线性非局部方程的更高正则性。虽然对于具有 VMO 系数的相应局部椭圆方程来说,只能获得更高的可积性,但在我们的非局部设置中,我们还能够证明大量的更高的可微性,因此我们的结果在某种意义上是纯粹的非局部类型。通过嵌入,我们还获得了此类非局部方程更高的 H'older 正则性。
We prove higher regularity for nonlinear nonlocal equations with possibly discontinuous coefficients of VMO-type in fractional Sobolev spaces. While for corresponding local elliptic equations with VMO coefficients it is only possible to obtain higher integrability, in our nonlocal setting we are able to also prove a substantial amount of higher differentiability, so that our result is in some sense of purely nonlocal type. By embedding, we also obtain higher H"older regularity for such nonlocal equations.
