چکیده
We analyze the strong coupling behavior of the large N gauge theories in 4-dimensions with N = 4 supersymmetry by making use of S-duality. We show that at large values of the coupling constant λ = g YMN the j-th non-planar amplitude fj(λ) (j = 0, 1, 2 . . .) behaves as fj(λ) ≈ λ j . Implication of this behavior is discussed in connection with the supergravity theory on AdS5×S 5 suggested by the CFT/AdS correspondence. S-duality of the gauge theory corresponds to the duality between the closed and open string loop expansions in the gravity/string theory.

Two Dimensional Mirror Symmetry from M-theory
We construct two dimensional gauge theories with N = (4, 4) supersymmetry from branes of type IIA string theory. Quantum effects in the two dimensional gauge theory are analyzed by embedding the IIA brane construction into M-theory. We find that the Coulomb branch of one theory and the Higgs branch of a mirror theory become equivalent at strong coupling. A relationship to the decoupling limit o...
متن کاملAspects of Large N Gauge Theory Dynamics as Seen by String Theory
In this paper we explore some of the features of large N supersymmetric and nonsupersymmetric gauge theories using Maldacena’s duality conjectures. We shall show that the resulting strong coupling behavior of the gauge theories is consistent with our qualitative expectations of these theories. Some of these consistency checks are highly nontrivial and give additional evidence for the validity o...
متن کاملDuality and Dynamical Supersymmetry Breaking in Spin(10) with a Spinor
We study N = 1 supersymmetric Spin(10) chiral gauge theories with a single spinor representation and N vector representations. We present a dual description in terms of an N = 1 supersymmetric SU(N − 5) chiral gauge theory with a symmetric tensor, one fundamental and N antifundamental representations. The Spin(10) theory with N = 0 breaks supersymmetry at strong coupling; we study how this aris...
متن کاملExtended Supersymmetric Moduli Space and a SUSY/Non-SUSY Duality
We study N = 1 supersymmetric U(N) gauge theories coupled to an adjoint chiral field with superpotential. We consider the full supersymmetric moduli space of these theories obtained by adding all allowed chiral operators. These include higher-dimensional operators that introduce a field-dependence for the gauge coupling. We show how Feynman diagram/matrix model/string theoretic techniques can a...
متن کاملADS / CFT String Duality and Conformal Gauge Theories
Compactification of Type IIB superstring on an AdS5 × S 5/Γ background leads to SU(N) gauge field theories with prescribed matter representations. In the ’t Hooft limit of large N such theories are conformally finite. For finite N and broken supersymmetry (N = 0) I derive the constraints to be twoloop conformal and examine the consequences for a wide choice of Γ and its embedding Γ ⊂ C3(⊃ S5).
