关于加权图上拉普拉斯算子自伴扩张的一个注记

泛函分析 2013-07-02 v2

摘要

我们研究加权图上拉普拉斯算子的自伴扩张与 Markov 扩张的唯一性。首先证明,对于局部有限图和某类度量,图的完备性蕴含这些扩张的唯一性。此外,当图非度量完备且 Cauchy 边界具有有限容量时,我们刻画了 Markov 扩张的唯一性。

17 pages. The assumption of "finite jump size" found in Theorems 1 and 2 in the previous version has been replaced by a weaker condition concerning the newly introduced notion of a "combinatorial neighborhood" in Theorem 1 and has been removed altogether from Theorem 2. Some references added. Final version to appear in J. Funct. Anal
