Extremal solutions to a class of multivalued integral equations in Banach space. (1992) - Aizicovici, Sergiu
Abstract : We consider a nonlinear Volterra integral inclusion in a Banach space. We establish the existence of extremal integral solutions, and we show that they are dense in the solution set of the original equation. As an important application, we obtain a “bang-bang” theorem for a class of nonlinear, infinite dimensional control systems.
