Contents
The general the aim of this course is to give understanding of the importance of symmetries in physics and how these can be described using group theory
The course will cover the following topics:
- The definition of a group and a representation
- The permutation group and other discrete groups, discrete symmetries in physics such as point groups
- Continuous groups (Lie groups), such as O(N), SO(N), U(N), SU(N), in particular SU(2), SU(3) and their importance in particle physics
- The Wigner-Eckart's theorem, Clebsch-Gordan coefficients and Young tableaux
- Casimir operators, roots, weights and the Cartan subalgebra, classification of Lie algebras with finite dimension
- The Lorentz group and the Poincaré group
