Kvantová mechanika a elektrodynamika

This book explains the basic principles and approximation methods of quantum mechanics, focusing on the use of symmetries in the solution of practical problems. It demonstrates that symmetries enable elegant solutions to problems that can be solved accurately, but that they significantly simplify the solution of problems that must be solved by approximation.
In addition, with a minimum of necessary formalism, it presents an introduction to quantum electrodynamics and its use for low energy physics. It systematically analyzes the influence of relativist, magnetic and quantum-electrodynamic effects on atomic spectra.
A second, revised edition.
