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.
