The Bulletin of Dnipropetrovsk University. Series: “Communications in Mathematical Modeling and Differential Equations Theory” (shortly “BDU-Modelling”) is concerned with the theory and the application of partial differential equations, dynamical systems, optimal control theory and other related topics. The goal is to provide a complete and reliable source of mathematical methods and results in this field. The journal will also accept papers from some related fields such as functional analysis, probability theory and stochastic analysis, inverse problems, optimization, numerical computation, mathematical finance, game theory, system theory, etc., provided that they have some intrinsic connections with control theory and differential equations.
