图上的Laplace算子和Dirac算子

Laplace and Dirac Operators on Graphs

Beata Casiday, Ivan Contreras, Thomas Meyer, Sabrina Mi, Ethan Spingarn

摘要:

拉普拉斯和狄拉克算子的离散版本已在统计力学和量子场论的组合模型的背景下进行了研究。在本文中,我们介绍了几个变化的拉普拉斯和狄拉克运营商的图,我们调查的薛定谔和狄拉克方程的图论版本。我们提供了一个组合的解释方程的解决方案,我们证明了格图上的狄拉克算子,以及图克利福德代数的胶合身份。

英文摘要:

Discrete versions of the Laplace and Dirac operators haven been studied in the context of combinatorial models of statistical mechanics and quantum field theory. In this paper we introduce several variations of the Laplace and Dirac operators on graphs, and we investigate graph-theoretic versions of the Schrödinger and Dirac equation. We provide a combinatorial interpretation for solutions of the equations and we prove gluing identities for the Dirac operator on lattice graphs, as well as for graph Clifford algebras.
