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.

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.

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 m<
