Some specific classes of relations, a review


  • Daniel Abraham Romano


In this paper, the concepts of several new classes of relations on
sets are presented introduced by this author in the previous ve years. The following classes of relations have been introduced and partly described in several his articles: the class of quasi-regular, the class of quasi-conjugative, the class of quasi-normal and the class of normally conjugative relations.
