我们建立了一个边界Harnack原则的一大类从属布朗运动,包括混合的对称稳定过程,在κ-胖开集(断开类似的约翰域)。作为边界Harnack原理的一个应用,我们用它们的欧氏边界确定了有界κ-胖开集关于这些过程的Martin边界和极小Martin边界.
We establish a boundary Harnack principle for a large class of subordinate Brownian motions, including mixtures of symmetric stable processes, in κ-fat open sets (disconnected analogue of John domains). As an application of the boundary Harnack principle, we identify the Martin boundary and the minimal Martin boundary of bounded κ-fat open sets with respect to these processes with their Euclidean boundaries.
