N=2 Curves and a Coulomb Phase in N=1 SUSY Gauge Theories with Adjoint and Fundamental Matters
T. Kitao, S. Terashima, S. -K. Yang
We study low-energy effective superpotentials for the phase with a confined photon in N=1 supersymmetric gauge theories with an adjoint matter and fundamental flavors $Q, \tild…
Spin- generalization of fractional exclusion statistics
T. Fukui, N. Kawakami, S. -K. Yang
We study fractional exclusion statistics for quantum systems with SU(2) symmetry (arbitrary spin ), by generalizing the thermodynamic equations with squeezed strings proposed by…
Exact Critical Exponents for Pseudo-Particles in the Kondo Problem
S. Fujimoto, N. Kawakami, S. -K. Yang
Exact critical exponents of the Green functions for pseudo-fermions and slave bosons in the SU() Anderson model with are obtained by using the Bethe ansatz…
Topological -Models and Large- Matrix Integral
T. Eguchi, K. Hori, S. -K. Yang
In this paper we describe in some detail the representation of the topological model in terms of a matrix integral which we have introduced in a previous article. We first d…
The Topological CP^1 Model and the Large-N Matrix Integral
T. Eguchi, S. -K. Yang
We discuss the topological model which consists of the holomorphic maps from Riemann surfaces onto . We construct a large- matrix model which reproduces precisely t…
On the Genus Expansion in the Topological String Theory
T. Eguchi, Y. Yamada, S. -K. Yang
A systematic formulation of the higher genus expansion in topological string theory is considered. We also develop a simple way of evaluating genus zero correlation functions. At h…
