 Synopsis:

The lecture  preferably for the students of Mathematical Physics  is aimed to introduce them to advanced topics connected with applications of group theory in quantum physics. Starting with the Wigner theorem on symmetry operations in quantum physics, the classification of projective representations of Lie groups as well as the superselection rules will be dealt with. The groups important in physics – the Euclid, the Poincaré and the Galilei group – will be treated by Mackey’s method of induced representations.
