Connectedness of the solution sets of inclusions

E. S. Zhukovskiy

Derzhavin Tambov State University, Tambov, Russia

Abstract: A research scheme for investigating the connectedness of the set of solutions of an inclusion in a topological space is proposed. It is applied to analyze the fixed-point set of a Volterra set-valued map in the space of continuous functions $C$; conditions for it to be connected in the norm and weak topology of $C$ are obtained. On this basis conditions are found which ensure that the solution set of Hammerstein's delay integral inclusion is connected.
Bibliography: 14 titles.

Keywords: connectedness, topological space, Volterra set-valued map, fixed point.
