In this paper we describe the varieties of commutative semigroups that are meet-and joinirreducible in the lattice of the varieties of commutative semigroups. We apply the method of A. Kisielewicz [Trans. Amer. Math. Soc. 342 (1994) 275-305]. This leads to investigation of the covering relation in t

We investigate the structure of groups satisfying a positi¨e law, that is, an identity of the form u ' ¨, where u and ¨are positive words. The main question here is whether all such groups are nilpotent-by-finite exponent. We answer this question affirmatively for a large class C C of groups includi
