ABSTRACT

In this paper we give a full description of idempotent elements of the semigroup B_X (D), which are defined by semilattices of the class <span "="">∑₁ (X, 10). For the case where X is a finite set we derive formulas by means of which we can calculate the numbers of idempotent elements of the respective semigroup.
