In order to study infinite-dimensional Lie algebras with root space decomposition as finite-dimensional simple Lie algebras，Victor Kac and Robert Moody independently introduced Lie algebras associated
This book provides explicit representations of finite-dimensional simple Lie algebras, related partial differential equations, linear orthogonal algebraic codes, combinatorics and algebraic varieties,
This book presents the various algebraic techniques for solving partial differential equations to yield exact solutions, techniques developed by the author in recent years and with emphasis on physica
