Standard Representations of Some Affine Lie Algebras.e. A = (a.) is an n × n integral matrix satisfying: (1) a. = 2, for ail i, (2) a. ? 0, for all i ≠ j, and (3) a. = 0 ? a. = 0 for all i ≠ j. The algebra L(A) is not necessarily finite-dimensional. Two GCM’s A = (a.) and B = (b.) are called . if there is a permutation π of the indices such that b. =

Some Applications of Vertex Operators to Kac-Moody Algebrasdule in the principal realization given by Lepowsky and Wilson [13], one may use vertex operators to describe the decomposition . of V ? V into symmetric tensors S(V) and antisymmetric tensors A(V). This turns out to be precisely the decomposition of V ? V into two “strings” of level two standard A.

A Brief Introduction to the Finite Simple Groups mathematical relationship. Because many conference participants have not worked in abstract algebra, a few brief statements about the current state of things in finite simple group theory seems in order. A number of recent articles [Gr4] [Gr5] and the book of Gorenstein [Go2] go into this subject i

A Moonshine Module for the Monsterof the classification theorem was completed. This unique proof, comprising several thousand pages of published articles and preprints, leads to the following list of finite simple groups (see [12] for the details): the groups of Lie type, the alternating groups and the 26 sporadic groups. While each

The Riemann-Hilbert Decomposition and the KP Hierarchy which is holomorphic and invertible on C, find the decomposition of H(ζ) into a product of matrix functions, X.(ζ) . where X.(ζ) (resp. X.(ζ)) is holomorphic and invertible in the inner (resp. outer) domain of C.”

Supersymmetric Yang-Mills Fields as an Integrable System and Connections with Other Non-Linear Systeoody, and Bianchi-Backlund transformations, are discussed for the constraint equations of the supersymmetric Yang-Mills fields. For N?3 these constraint equations give equations of motion of the fields, thus integrating the constraint equations is equivalent to integrate the equation of motion. Furt
