论文摘要
在本文中，审查了一些以协变方式执行量子场理论计算的技术。特别是背景场量表，突出显示了ZETA函数正则化和热核方法。还详细重复了热量内核的少量适当时间扩展的Schwinger-de Witt系数的一些详细计算。这项工作报告了恩里克·阿尔瓦雷斯（Enriqueálvarez）在马德里的IFT-UAM-CSIC发表的讲座。
In this paper some techniques useful to perform quantum field theory computations in a covariant manner are reviewed. In particular the background field gauge, the zeta function regularization and the heat kernel approach are highlighted. Some detailed calculations of the Schwinger-de Witt coefficients of the small proper time expansion of the heat kernel are also repeated in detail. This work reports lectures given by Enrique Álvarez at the IFT-UAM-CSIC in Madrid.
