2019, Volume 306

The bulk of the volume is composed of papers devoted to problems of modern mathematical physics. Among the subjects of the papers are current models of mathematical physics as well as problems of the theory of partial differential equations, the theory of generalized functions, and the theory of quantum systems. The research presented in the papers uses the methods of functional analysis, differential geometry, $p$-adic analysis, probability theory, and complex analysis. All papers have been prepared by leading experts who are actively working in their scientific field. On the whole, the volume is intended for a wide range of readers; it gives a fairly complete picture of the current state of mathematical physics.
