Abstract

In this paper we deal with the variation of a set multifunction with respect to a set-norm on the family of non-empty subsets of a commutative semigroup with unity and present some results concerning the transfer of some properties (such as fuzzyness, continuity from below, null-additivity, null-null-additivity) between a set multifunction and its variation.
