The purpose of this paper is to prove various selection and fixed point theorems for r-open graph multifunctions.156 J. F. McCLENDONSection 1 gives definitions and some needed results on fibrations.Selection theorems are given in §2 and fixed point theorems in §3.Section 4 discusses generalizations.
