F - Theory , T - Duality on K 3 Surfaces and N = 2 Supersymmetric Gauge Theories in Four Dimensions

چکیده
We construct T-duality on K3 surfaces. The T-duality exchanges a 4-brane R-R charge and a 0-brane R-R charge. We study the action of the T-duality on the moduli space of 0-branes located at points of K3 and 4-branes wrapping it. We apply the construction to F-theory compactified on a Calabi-Yau 4-fold and study the duality of N = 2 SU(N c) gauge theories in four dimensions. We discuss the generalization to the N = 1 duality scenario.

S-duality in N=2 supersymmetric gauge theories
A solution to the infinite coupling problem for N = 2 conformal supersymmetric gauge theories in four dimensions is presented. The infinitely-coupled theories are argued to be interacting superconformal field theories (SCFTs) with weakly gauged flavor groups. Consistency checks of this proposal are found by examining some low-rank examples. As part of these checks, we show how to compute new ex...
متن کاملManifolds of Fixed Points and Duality in Supersymmetric Gauge Theories
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 existen...
متن کاملBranes and N=1 Duality in String Theory
We propose a construction of dual pairs in four dimensional N=1 supersymmetric Yang-Mills theory using branes in type IIA string theory. Supersymmetric gauge theories invariant under eight or sixteen supercharges (e.g. N=2 and N=4 supersymmetric Yang-Mills theories in four dimensions, respectively) have been intensively studied in the last few years. Many of the diverse strong coupling phenomen...
متن کاملNew Superconformal Field Theories in Four Dimensions and N = 1 Duality
Recently, developments in the understanding of low-energy N = 1 supersymmetric gauge theory have revealed two important phenomena: the appearance of new four-dimensional superconformal field theories and a non-Abelian generalization of electric-magnetic duality at the IR fixed point. This report is a pedagogical introduction to these phenomena. After presenting some necessary background materia...
متن کاملMaximally supersymmetric string theories in D<10.
The existence of maximally supersymmetric solutions to heterotic string theory that are not toroidal compactifications of the ten-dimensional superstring is established. We construct an exact fermionic realization of an N=1 supersymmetric string theory in D=8 with non-simply-laced gauge group Sp(20). Toroidal compactification to six and four dimensions gives maximally extended supersymmetric th...
