Abstract

We investigate possible extensions of various types of continuity of aggregation functions
to their super- and sub-additive transformations. More speci cally, we examine lifts
of classical, uniform, Lipschitz and Holder continuities and di erentiability. The classical,
uniform, and Lipschitz continuities turn out to be preserved by super- and sub-additive
transformations (albeit for uniform continuity and the super-additive case we prove it
only in dimension one), while the Holder continuity and di erentiability are not.
