**Conformal Field Theory on the Plane**

by

**Sylvain Ribault**-

**arXiv**

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.

**Introduction to Symplectic Field Theory**

by

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

**arXiv**

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.

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

by

**Timothy Cohen**-

**arXiv.org**

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.
