非局部对称Dirichlet型的内蕴度量及其对spectral theory的应用

Intrinsic metrics for non-local symmetric Dirichlet forms and applications to spectral theory

Rupert L. Frank, Daniel Lenz, Daniel Wingert

摘要:

我们提出了一个研究什么可以被称为一个内在的度量一般定期狄利克雷形式。对于这样的形式,我们然后证明一个Rademacher型定理。对于强局部形式,我们证明了存在一个最大的内在度量(在弱连续性条件下)和Dirichlet形式的绝对连续的跳跃核,我们的内在度量的某些积分的界限。然后,我们转向应用光谱理论和提供(措施扰动)一般经常狄利克雷形式的Allegretto Piepenbrinck型定理,这是基于基态变换,和Shnol型定理。我们的设置包括拉普拉斯流形上,图和$α$稳定的过程。

英文摘要:

We present a study of what may be called an intrinsic metric for a general regular Dirichlet form. For such forms we then prove a Rademacher type theorem. For strongly local forms we show existence of a maximal intrinsic metric (under a weak continuity condition) and for Dirichlet forms with an absolutely continuous jump kernel we characterize intrinsic metrics by bounds on certain integrals. We then turn to applications on spectral theory and provide for (measure perturbation of) general regular Dirichlet forms an Allegretto-Piepenbrinck type theorem, which is based on a ground state transform, and a Shnol type theorem. Our setting includes Laplacian on manifolds, on graphs and $α$-stable processes.
