Abstract

By using some results on translation and superadditive relations, we give some relational reformulations of the Phelps–Cardwell lemma in terms of open and closed surroundings. These reformulations have mainly been suggested by a unifying scheme for continuities of relations in relator spaces and a projective generation of translation relators by superadditive relations.

Keywords:

Translation and superadditive relations, open and closed surroundings, Phelps–Cardwell lemma
