Some properties of set-valued sine families


Abstract. Let \(\{F_t : t \geq 0\}\) be a family of continuous additive set-valued functions defined on a convex cone \(K\) in a normed linear space \(X\) with nonempty convex compact values in \(X\). It is shown that (under some assumptions) a regular sine family associated with \(\{F_t : t \geq 0\}\) is continuous and \(\{F_t : t \geq 0\}\) is a continuous cosine family.
Keywords: set-valued sine and cosine families, continuity of sine families, Hukuhara differences, concave set-valued functions.
