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.
