Symmetries in Physics (2022-2023) Here you can find the problems for the symmetries in physics lectures. I thank M. Gessner, F. Chevy and L. Hruza for having prepared most of the problems and solutions. TD1 : Finite Groups (problems, solutions) TD2 : Normal subgroups and Quotient groups (problems, solutions) TD3 : Orthogonal groups (problems, solutions) TD4 : Symmetric groups (problems, solutions) TD5 : Representations of Finite Groups (problems, solutions) TD6 : SO(n) and Wave Functions (problems, solutions) TD7 : Heisenberg and Symplectic Groups (problems, solutions) TD8 : Tensor Products (problems, solutions)
