Continuous Symmetries, Lie Algebras, Differential Equations And Computer Algebra (2nd Edition)This textbook comprehensively introduces students and researchers to the application of continuous symmetries and their Lie algebras to ordinary and partial differential equations. Covering all the modern techniques in detail, it relates applications to cutting edge research fields such as Yang Mills theory and string theory. Aimed at readers in applied mathematics and physics rather than pure mathematics, the material is ideally suited to students
