Quantum Groups in Lattice Models first chapter presents the Bethe ansatz technique applied to the XXZ chain. The second is an introduction to the technique of diagonalisation of transfer matrices in the six vertex model case. The third is devoted to the study of some quadratic algebras. More specifically we consider the examples o

Correlation Functions of Local Operators in 2D Gravity Coupled to Minimal Mattern the theory of 2D gravity coupled to the minimal models of matter..Here I would like to discuss the results available on the calculation of the correlation functions of local operators in the theory of 2D gravity coupled to the minimal matter, in the approach of conformal field theory [1, 2, 3, 4].

A classical limit of a .-algebra can be identified with the center of the universal enveloping algebra of the corresponding affine Kac-Moody algebra. This gives some inf
