On almost everywhere K-additive set-valued maps

Eliza Jabłońska Logo ORCID

Abstract

Let X be an Abelian group, Y be a commutative monoid, K ⊂Y be a submonoid and F : X → 2\ {∅} be a set-valued map. Under some additional assumptions on ideals ℐin X and ℐin X2, we prove that if F is ℐ2-almost everywhere K-additive, then there exists a unique up to K K-additive set-valued map G : X → 2\{∅} such that F = G ℐ1-almost everywhere in X. Our considerations refers to the well known de Bruijn’s result [1].
