Mathematical methods for physics : an introduction to group theory topology and geometry The book steadily develops the key concepts required for an understanding of symmetry principles and topological structures such as group theory differentiable manifolds Riemannian geometry and Lie algebras. Based on a course for senior undergraduate students of physics it is written in a clear pedagogical style and would also be valuable to students in other areas of science and engineering. The material has been subject to more than twenty years of feedback from students ensuring that explanations and examples are lucid and considered and numerous worked examples and exercises reinforce key concepts and further strengthen readers understanding. This text unites a wide variety of important topics that are often scattered across different books and provides a solid platform for more specialized study or research Group theory Representation theory of groups Differentiable manifolds Riemannian geometry Semisimple Lie algebras and their unitary representations.
