A condition for constructing a right closure—semigroup (RC-semigroup) by an operator on N
(2, 2, 0) algebra is investigated. Some properties of RC semigroup of N (2, 2, 0) algebra …

Restriction semigroups model algebras of partial maps under composition and domain.
Here we consider restriction semigroups for which the usual Boolean operations on …

The Kuratowski Closure-Complement Theorem 1.1.[29] If (X; T) is a topo-logical space and A
_ X then at most 14 sets can be obtained from A by taking closures and complements …

In Section 2 of the present paper, we introduce the concept of pseudocomplementation for
semirings and show the semiring version of some known results in lattice theory. We also …

We examine the problem of representing semigroups as binary relations, partial maps and
injective functions, with the constraint that certain pre-designated idempotent elements must …

This thesis collects together four sets of results, produced by investigating modifications, in
four distinct directions, of the following. Some set-theoretic operations on partial functions …

We define antidomain operations for algebras of multiplace partial functions. For all
signatures containing composition, the antidomain operations and any subset of …
