Complete semigroups of binary relations defined by $X$-semilattices of unions
Ya. Diasamidze, Sh. Makharadze Batumi Shota Rustaveli State University
Abstract:
This paper is devoted to some results from the book “Complete Semigroups of Binary Relations”, which is not published yet. Conditions of divisibility of binary relations, idempotents, regular elements, one-side units, and one-side zeros are described. Finite $X$-semilattices and unions are characterized. Methods of finding formulas for counting the number of idempotents and regular elements are given.
