Covariant techniques in quantum field theory
Alvarez, Enrique.

Covariant techniques in quantum field theory[electronic resource] /by Enrique Alvarez, Jesus Anero. - Cham :Springer International Publishing :2022. - vii, 90 p. :ill., digital ;24 cm. - SpringerBriefs in physics,2191-5431. - SpringerBriefs in physics..

Introduction and generalities -- The background field approach in quantum field theory -- The one loop effective action -- Divergences out of Schwinger-DeWitt coefficients -- A One-loop divergences in first order Einstein-Hilbert gravity.

The purpose of this book is to illustrate some of the most important techniques which are helpful in combinatorial problems when computing quantum effects in covariant theories, like general relativity. In fact, most of the techniques find application also in broader contexts, such as low energy effective (chiral) Lagrangians or even in specific problems in condensed matter. Some of the topics covered are: the background field approach and the heat kernel ideas. The arguments are explained in some detail and the presentation is meant for young researchers and advanced students who are starting working in the field. As prerequisite the reader should have attended a course in quantum field theory including Feynman's path integral. In the Appendix a nontrivial calculation of one-loop divergences in Einstein-Hilbert gravity is explained step-by-step.
