This collection of articles is devoted to one of the most interesting problems of modern theoretical physics - the development and application of the coherent state method in the problems of quantum theory. The articles discuss in detail the physical properties of coherent states, as well as the mathematical apparatus associated with them. It provides an overview of various aspects of the application of the representation of coherent states in quantum field theory, quantum optics, superfluidity theory, magnetism theory and in the fundamental problems of quantum mechanics itself. Describes the results, successes and prospects of this new, important area of theoretical physics, which did not have time to find reflections in monographs.
