Unification in Varieties of Groups: Nilpotent Varieties

Canadian Journal of Mathematics, 1994
Abstract In this paper we show that any system of equations over a free nilpotent group of class c is either unitary or miliary. In fact, such a system either has a most general solution (akin to the most general solution of a system of linear dipohantine equations), or every solution

A variety of groups

Mathematical Proceedings of the Cambridge Philosophical Society, 2005
The main result of the paper under review is the following: Theorem 1.5. For any positive integers \(k\) and \(n\) there exists \(t\) depending only on \(k\) and \(n\) such that the class of all groups \(G\) satisfying the identity \(w_t^n\equiv 1\) and having \(\gamma_k(G)\) locally finite is a variety, where the symbol \(w_j\) denotes a word that is ...

VARIETIES OF GROUP REPRESENTATIONS

Russian Mathematical Surveys, 1977
A group representation is a pair (A,Γ), where A is a module over a commutative ring K with identity and Γ is a group that acts on A. In the category of group representations over a fixed K, both A and Γ are variable. We study varieties in this category. This paper is a survey of results and problems in this area and connections with other topics.

On Metanilpotent Varieties of Groups

Canadian Journal of Mathematics, 1970
Let denote the variety of all groups which are extensions of a nilpotent-of-class-c group by a nilpotent-of-class-d group, and let denote the variety of all metabelian groups. The main result of this paper is the following theorem.THEOREM. Let be a subvariety of which does not contain .
