Regular Elements Of Semigroups B_x(d) Defined By Generalized Elementary B_x(d)-semilattices Of Unions

摘要

In the paper, the class of complete semigroups of binary relations is considered, each of whose elements is defined by a complete B_X(D)-semilattice of unions which belongs to the class of generalized elementary X-semilattices. Regular elements are described for each semigroup of this class.
