Elke Franz,Anja Jerichow,Andreas PfitzmannIn this section all multivalued mappings are assumed to have convex values in some Banach space. We begin with the union of Theorems (1.1) and (1.5) .

Zero-Dimensional Selection Theoremof of Convex-valued theorem, but without any partitions of unity. As in the previous paragraph we begin (see Section 1) by the necessity conditions for solvability of the selection problem for an arbitrary closed-valued mapping. Our proof of Theorem (2.4) follows the original one . The converse theorem (2.1) is a well-known folklore result.
