N=2 Superconformal Theories and their Integrable Deformations
J. -B. Zuber
Abstract
After a short review of the algebraic setting of N=2 superconformal field theories, their chiral ring and their perturbations, I present some recent results on curious relations between the integrability of their perturbations and algebraic properties of their deformed chiral ring.
