Fusion of the -Vertex Operators and its Application to Solvable Vertex Models
Atsushi Nakayashiki
We diagonalize the transfer matrix of the inhomogeneous vertex models of the 6-vertex type in the anti-ferroelectric regime intoducing new types of q-vertex operators. The special…
Coherent states, Path integral, and Semiclassical approximation
K. Funahashi, T. Kashiwa, S. Sakoda +1
Using the generalized coherent states we argue that the path integral formulae for and (in the discrete series) are WKB exact,if the starting point is expressed a…
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…
Two-dimensional SU(N) Gauge Theory on the Light Cone
Takanori Sugihara, Masayuki Matsuzaki, Masanobu Yahiro
Two-dimensional SU() gauge theory is accurately analyzed with the light-front Tamm-Dancoff approximation, both numerically and analytically. The light-front Einstein-Schrödinger…
Ordering, symbols, and finite-dimensional approximations of path integrals
T. Kashiwa, S. Sakoda, S. V. Zenkin
We derive general form of finite-dimensional approximations of path integrals for both bosonic and fermionic canonical systems in terms of symbols of operators determined by operat…
