摘要
Glazman-Povzner-Wienholtz 定理指出,流形的完备性,结合 Schr"odinger 算子 的半有界性以及对 的适当局部正则性假设,可保证其本质自伴性。我们的目标是将该结果推广到图上的 Schr"odinger 算子。我们首先得到度量图上 Schr"odinger 算子的相应定理,特别允许分布势 。此外,我们利用最近发现的度量图与加权图上 Schr"odinger 算子之间的联系,来证明 Glazman-Povzner-Wienholtz 定理的离散版本。

24 pages; After submission we learned that the discrete version of the Glazman-Povzner-Wienholtz theorem (Theorem 6.1) was proved earlier by a different approach in arXiv:1301.1304 (see Theorem 2.16 there)
