Abstract
[en] The present work is an attempt to introduce a novel axiomatic formulation of Quantum Field Theory proposed by Kevin Costello in [Cos11. Far from being exhaustive, we aim to present the main results and constructions, followed by calculations in this formalism that match the physics literature. We try to give a pedagogical introduction, providing all the definitions that an undergraduate student would need to understand the key concepts. We start by defining the simplest kinds of quantum field theories and how to make sense of divergent quantities. As we move forward, we try to generalize these definitions to more and more general classes of theories. The endpoint of this work is to use Costello's machinery to define the Yang-Mills theory on $\mathbb{R}^4$ and prove that it is perturbatively renormalizable.
