The main subject of the groop is to study properties of functions and other mathematical objects from the points of the theory of functional differential equations and complex analysis of one or several variables. We develop the statistical methods in the fields of multivariate analysis, sequential analysis and design of experiments. We also research the optimality and the robustness of the methods, and the asymptotic theory in mathematical statistics. We study numerical methods of partial differential equations and integral equations. We also study language systems and theory of neural networks.
