Markus Faustmann, Carlo Marcati, Jens Markus Melenk, Christoph Schwab

AI总结:

本文通过Caffarelli-Silvestre延拓和Caccioppoli不等式,证明了多边形中积分分数阶拉普拉斯算子Dirichlet问题解的加权解析正则性。

摘要:

我们证明了在解析右边项下,多边形中积分分数阶拉普拉斯算子Dirichlet问题解的加权解析正则性。通过Caffarelli-Silvestre延拓对问题进行局部化,研究延拓解的切向可微性,随后基于顶点、边及边-顶点邻域二进分解上的Caccioppoli不等式进行自举。

英文摘要:

We prove weighted analytic regularity of solutions to the Dirichlet problem for the integral fractional Laplacian in polygons with analytic right-hand side. We localize the problem through the Caffarelli-Silvestre extension and study the tangential differentiability of the extended solutions, followed by bootstrapping based on Caccioppoli inequalities on dyadic decompositions of vertex, edge, and edge-vertex neighborhoods.
