The collection contains works B. A. Foka on secondary quantization and quantum electrodynamics, performed by him in 1928-1937. The significance of these works B. A. Fock has especially increased in the present time due to the fact that the theory of wave fields has become one of the most relevant sections of modern theoretical physics. However, the study of the works of academia. In. A. The focus on quantum electrodynamics is hampered by the fact that they are published in foreign languages in journals that are difficult to obtain. The publication simplifies this task. The foreword to the collection briefly highlights the development of B. ideas and methods A. Fock in modern quantum field theory. The book is designed for specialists working in the field of theoretical physics, graduate students and senior students .
