分数阶系统的内部正则性

Interior regularity for fractional systems

Luis Caffarelli, Gonzalo Davila

摘要:

本文研究了2s阶椭圆型分数阶方程组$s \in (0, 1)$解的正则性,其中右端f依赖于一个非局部梯度,并且具有与非局部算子相同的标度性质.在系统的某些结构条件下,我们证明了内部Hölder估计的精神[1]。我们的结果在s中是稳定的,这使得我们恢复了由于S而得到的椭圆方程组的经典结果。Hildebrandt和K. Widman [6]和M. Wiegner [9].

英文摘要:

We study the regularity of solutions of elliptic fractional systems of order 2s, $s \in (0, 1)$, where the right hand side f depends on a nonlocal gradient and has the same scaling properties as the nonlocal operator. Under some structural conditions on the system we prove interior Hölder estimates in the spirit of [1]. Our results are stable in s allowing us to recover the classic results for elliptic systems due to S. Hildebrandt and K. Widman [6] and M. Wiegner [9].
