Subject:
Grid schemes for constructing value functions and guaranteeing feedbacks are elaborated for optimal control problems. Finite difference operators based on constructions of nonsmooth analysis are proposed for approximation of generalized derivatives in Hamilton–Jacobi equations. Convergence results for approximation schemes are proved and estimates of convergence are indicated. Differential inequalities in terms of conjugate derivatives are obtaibed for characterization of stability properties of the value function in infinitesimal form. Regularity conditions for the function of programming maximin are derived in terms of conjugate variables. These results are applied to solution of a series of problems of mathematical economics: dynamic bimatrix games, models of optimal economic growth, problems of dynamic vector optimization, game interaction of investment projects, repeating games of auction type for searching optimal solutions of multicriteria problems.
