On the minimax control problem for nonlinear operator-differential equations

We consider the problem of minimax control for objects describable by nonlinear operator-differential equations in Banach spaces with restrictions on the phase variables and controls. We prove solvability theorems. The method of proof is based on the theory of extremal problems for generalized operator-differential equations.Translated fromVychislitel'naya i Prikladnaya Matematika, Issue 71, 1990, pp. 114–119.
