Manifolds of Fixed Points and Duality in Supersymmetric Gauge Theories

概要

There are many physically interesting superconformal gauge theories in four dimensions. In this talk I discuss a common phenomenon in these theories: the existence of continuous families of infrared fixed points. Well-known examples include finite N = 4 and N = 2 supersymmetric theories; many finite N = 1 examples are known also. These theories are a subset of a much larger class, whose existence can easily be established and understood using the algebraic methods explained here. A relation between the N = 1 duality of Seiberg and duality in finite N = 2 theories is found using this approach, giving further evidence for the former. This talk is based on work with R. Leigh.
