Tiziana Cardinali, Francesca Papalini Annales Polonici Mathematici 58 (1993), 185-192 DOI: 10.4064/ap-58-2-185-192


We present a stability theorem of Ulam-Hyers type for K-convex set-valued functions, and prove that a set-valued function is K-convex if and only if it is K-midconvex and K-quasiconvex.
