Introduction to Renormalisation
by Joao F. Melo
Publisher: arXiv 2019
Number of pages: 68
Description:
These are introductory lecture notes aimed at beginning graduate students covering fundamental concepts and ideas behind the renormalisation group. Our main goal is to motivate it and then explore its consequences, in the context of quantum field theory. We shall reproduce the standard results without needing any mention of cancellation of infinities.

Introductory Lectures on Topological Quantum Field Theoryby Nils Carqueville, Ingo Runkel - arXiv.org
These notes offer a lightening introduction to topological quantum field theory in its functorial axiomatisation assuming no or little prior exposure. We highlight the algebraic formulation emerging from a formal generators-and-relations description.

Quantum Field Theoryby A.N. Schellekens
All particles in the standard model correspond to some field in a quantum field theory. Our task is to understand how this works, how to describe interactions of these particles using quantum field theory, and how to compute various processes.

Introductory Lectures on Quantum Field Theoryby Luis Alvarez-Gaume, Miguel A. Vazquez-Mozo - arXiv
In these lectures we present a few topics in Quantum Field Theory in detail. Some of them are conceptual and some more practical. They have been selected because they appear frequently in current applications to Particle Physics and String Theory.
