Magic N-Cubes Form a Free Monoid
In this paper we prove a conjecture stated in an earlier paper [A-L]. The conjecture states that with respect to a rather natural operation, the set of N-dimensional magic cubes forms a free monoid for every integer N ? 1.

. Whereas pseudovarieties of commutative semigroups are known to be finitely based, the globals of monoidal pseudovarieties of commutative semigroups are shown to be finitely based (or of finite vertex rank) if and only if the index is 0, 1 or ...

The concept of regularity in Γ-semigroups is not very easy to deal with even though it shares some analogy with its analogue of semigroup theory. In this paper we establish a mechanism which translates the regularity in a Γ-semigroup (S,Γ) as the usual ...
