Particle interactions and quantum mechanics: Mathematical foundations

This review contains chapters from the first volume of S. S. Sannikov-Proskuryakov’s collected papers. The first and the second chapters are compilations of his early publications. The four papers included in Chapters 3–7 were written during the last years of his life. The most valuable results obtained by S. S. Sannikov-Proskuryakov can be useful for deep understanding of the current status and contemporary developments of high-energy physics.
