| Abstract : | Summary. We define here: mode Relation as a set of pairs, the domain, the codomain, and the field of relation; the empty and the identity relations, the composition of relations, the image and the inverse image of a set under a relation. Two predicates, = and ?, and three functions, ?, ? and \ are redefined. Basic facts about the above mentioned notions are presented., |
