In this note we establish some characterizations of (single valued) functions, that assume values in a Banach space, generating K-Schur concave sums. Moreover we prove that a set-valued function is K-concave if and only of it is K-t-concave and K-quasi concave (where t is a fixed number in (0,1)).

Abstract

In this note we establish some characterizations of (single valued) functions, that assume values in a Banach space, generating K-Schur concave sums. Moreover we prove that a set-valued function is K-concave if and only of it is K-t-concave and K-quasi concave (where t is a fixed number in (0,1)).
