Lie Algebraic Methods in Integrable Systems (eBook, ePUB)

• Format: ePub

Produktbeschreibung

Presents the basic techniques of using Lie algebraic concepts to explore the domain of nonlinear integrable systems. This book begins by establishing a practical basis in Lie algebra, including discussions of structure Lie, loop, and Virasor groups, quantum tori and Kac-Moody algebras, and gradation.
