**As Scales Become Separated: Lectures on Effective Field Theory**

by

**Timothy Cohen**-

**arXiv.org**,

**2019**

These lectures aim to provide an introduction to the philosophical underpinnings and technical features of Effective Field Theory. Improving control of S-matrix elements in the presence of a large hierarchy of physical scales is emphasized.

**Conformal Field Theory on the Plane**

by

**Sylvain Ribault**-

**arXiv**,

**2014**

We provide an introduction to conformal field theory on the plane in the conformal bootstrap approach. We introduce the bootstrap approach to quantum field theory, and how they apply to two-dimensional theories with local conformal symmetry.

**Conformal Field Theory, Tensor Categories and Operator Algebras**

by

**Yasuyuki Kawahigashi**-

**arXiv**,

**2015**

This is a set of lecture notes on the operator algebraic approach to 2-dimensional conformal field theory. Representation theoretic aspects and connections to vertex operator algebras are emphasized. No knowledge on operator algebras is assumed.

**Lecture Notes on Topological Field Theory**

by

**Jian Qiu**-

**arXiv**,

**2012**

These notes cover some topics in both the perturbative and non-perturbative topological Chern-Simons theory: the quantization of Chern-Simons theory, the use of surgery for computation, brief discussions about framings, eta invariants, etc.

**Yang Mills model of interacting particles in the classical field theory**

by

**Jean Claude Dutailly**-

**arXiv**,

**2011**

The purpose is to study interacting particles in the General Relativity context, by the principle of least action using purely classical concepts. The particles are described by a state tensor using a Clifford algebra for the kinematic part.

**An Introduction to Conformal Field Theory**

by

**Matthias R Gaberdiel**-

**arXiv**,

**1999**

A comprehensive introduction to two-dimensional conformal field theory is given. Conformal field theories have been at the center of attention during the last fifteen years since they are relevant for different areas of modern theoretical physics.

**Introduction to Symplectic Field Theory**

by

**Y. Eliashberg, A. Givental, H. Hofer**-

**arXiv**,

**2000**

We sketch in this article a new theory, which we call Symplectic Field Theory or SFT, which provides an approach to Gromov-Witten invariants of symplectic manifolds and their Lagrangian submanifolds in the spirit of topological field theory.

**Introduction to Effective Field Theory**

by

**C. P. Burgess**-

**arXiv**,

**2007**

This review summarizes Effective Field Theory techniques, which are the theoretical tools for exploiting the existence of hierarchies of scale in a physical problem. The general theoretical framework is described, and evaluated for a simple model.
