Content | The covered topics will include: (1) Basic notions in group theory: groups, subgroups, homomorphisms, products, cosets and quotients. (2) Basic notions in representation theory: group actions and representations, irreducibility, product representations, decompositions under subgroups. (3) Representation theory of discrete (finite) groups: Schur orthogonality relations, the regular representation, classification of irreducible representations. (4) Discrete groups: basic examples, Schoenflies notation, crystallographic point groups. (5) Lie groups: examples, Lie groups and Lie algebras, exponential map, ladder operators, root and weight lattices, classification of semisimple Lie algebras, representation theory of semisimple Lie groups/algebras, SO(n) and SU(n), the Lorentz group. Applications of group theory will be demonstrated with worked out physical examples; they include consideration of symmetries in mechanical systems, in crystals from Solid State Physics, degeneracies in spectra in Quantum Mechanics, and both global and local symmetries in Particle Physics. |
