论文摘要
我们审查并介绍了Feynman图的完整详细信息 - 基于基于热的非局部形式的基于基于热的非局部形式的计算，在大规模标量场的一环贡献中。该论文具有教学和介绍性的目的，旨在帮助读者更好地了解有关该主题的现有文献。该功能计算基于Avramidi和Barvinsky \＆Vilkovisky的溶液，用于热核，并在弯曲的时空中进行。重要的一点是，非本地性的主要结构与平面背景相同。
We review and present full detail of the Feynman diagram - based and heat-kernel method - based calculations of the simplest nonlocal form factors in the one-loop contributions of a massive scalar field. The paper has a pedagogical and introductory purposes and is intended to help the reader in better understanding the existing literature on the subject. The functional calculations are based on the solution by Avramidi and Barvinsky \& Vilkovisky for the heat kernel and are performed in curved spacetime. One of the important points is that the main structure of non-localities is the same as in the flat background.
