热核:固有时方法、Fock-Schwinger规范、路径积分表示与Wilson线

Heat kernel: proper time method, Fock-Schwinger gauge, path integral representation, and Wilson line

A. V. Ivanov, N. V. Kharuk

AI总结:

本文以热核固有时方法为对象,通过模型情形研究渐近展开与路径积分表示,证明Seeley-DeWitt系数的非递归公式及两种主要方法的等价性。

摘要:

固有时方法在现代数学和物理学中发挥着重要作用。它包含许多方法,每种方法都有其优缺点。本工作致力于描述一个模型情形,该情形反映了构造中的微妙之处,并可推广到更一般的情形(弯曲空间、带边界的流形),且包含两个相互关联的部分:渐近展开和路径积分表示。本文详细讨论了规范条件的重要性和有序指数的作用,给出了对角线上Seeley-DeWitt系数的一种新的非递归公式的证明,并利用指数公式证明了两种主要方法的等价性。

英文摘要:

The proper time method plays an important role in modern mathematics and physics. It includes many approaches, each of which has its pros and cons. This work is devoted to the description of one model case, which reflects the subtleties of construction and can be extended to a more general cases (curved space, manifold with boundary), and contains two interrelated parts: asymptotic expansion and path intergal representation. The paper discusses in details the importance of gauge conditions and role of the ordered exponentials, gives the proof of a new non-recursive formula for the Seeley-DeWitt coefficients on the diagonal, as well as the equivalence of the two main approaches using the exponential formula.
