Some properties of convex and $*$-concave multifunctions

Bożena Piątek

Abstract


We investigate some properties of {$*$}-concave and convex multifunctions on the real line with convex bounded closed values. In particularly we consider the Hadamard inequality and the Hardy--Little\-wood--P\'olya majorization theory in the case of multifunctions.
