The linearity of automorphism groups of relatively free groups
Mathematical Notes, 1995Let \({\mathcal N}_c\) be the variety of all nilpotent groups of class \(c\) (\(c\geq 1\)), \(\mathcal U\) be the variety of all abelian groups, \({\mathcal U}_k\) be the variety of all abelian groups of exponent \(k\), \({\mathcal B}_m\) be the variety of all locally finite groups of exponent \(m\) and \(\mathcal I\) be the variety of all groups.

Relatively free products of Magnus groups
Journal of Mathematical Sciences, 2006A group \(G\) is called a Magnus group if 1) \(\bigcap_{i=1}^\infty\gamma_iG=1\); 2) \(\gamma_iG/\gamma_{i+1}G\) are Abelian torsion free groups. It is shown that the class of Magnus \(\mathfrak{AN}_c\)-groups is closed with respect to \(\mathfrak{AN}_c\)-products.

Analytic relatively free pro-p groups
Journal of Group Theory, 2004An absolutely free pro-\(p\) group of rank greater than \(1\) is not \(p\)-adic analytic. In the paper under review it is shown that if a relatively free pro-\(p\) group is \(p\)-adic analytic, then it is topologically finitely generated and nilpotent-by-finite. This confirms a conjecture of A.~Shalev.

On the Group of Reduced Identities of Relatively Free Solvable Groups
Siberian Mathematical Journal, 2002The author uses the basic notions of algebraic geometry over a fixed group \(G\) [see \textit{G. Baumslag}, \textit{A. Myasnikov}, \textit{V. Remeslennikov}, J. Algebra 219, No. 1, 16-79 (1999; Zbl 0938.20020)]. A group \(H\) with fixed embedding \(G\to H\) is called \(G\)-group. Denote the free product \(G*F(X)\) by \(G[X]\).

Free Modules of Relative Invariants of Finite Groups
Studies in Applied Mathematics, 1989This paper addresses questions about when modules of relative invariants of a finite group G acting on a polynomial ring R are free over the ring of invariant polynomials RG. A converse (first obtained by Shchvartsman) is proven of a result asserting that these modules are always free when the group is generated by pseudoreflections. We also re‐prove

AUTOMORPHISMS OF CERTAIN RELATIVELY FREE GROUPS AND LIE ALGEBRAS
International Journal of Algebra and Computation, 2004For positive integers n and c, with n≥2, let Gn,c be a relatively free group of rank n in the variety N2A∧AN2∧Nc. It is shown that there exists an explicitly described finite subset Ω of IA-automorphisms of Gn,c such that the cardinality of Ω is independent upon n and c and the subgroup of the automorphism group Aut (Gn,c) of Gn,c generated by the ...

Relatively free, nearly nilpotent groups
Mathematical Notes of the Academy of Sciences of the USSR, 1972We show that a free nilpotent group of countable rank, as well as a free group of countable rank of the variety defined by the identity [[x1 x2,..., xn], [xn+1, xn+2]]=1, satisfies the maximal condition for normal subgroups admitting endomorphisms induced by order preserving one-to-one mappings of the set of free generators into itself.

ON THE BERGMAN PROPERTY FOR THE AUTOMORPHISM GROUPS OF RELATIVELY FREE GROUPS
Journal of the London Mathematical Society, 2006A group has the Bergman property. Also, we obtain a partial answer to a question posed by Bergman by establishing that the automorphism group of a free group of countably infinite rank is a group of uniformly finite width.

The Birkhoff-Neumann embedding of relatively free groups.
2006Let \(H\) be a finite group, let \(\mathbf V\) be the variety generated by \(H\) and for \(r\geq 1\) let \(G_r\) be the relatively free group in \(\mathbf V\) on \(r\) free generators. Results of \textit{G. Birkhoff} [Proc. Camb. Philos. Soc. 31, 433-454 (1935; Zbl 0013.00105)] and \textit{B. H. Neumann} [Math. Ann. 114, 506-525 (1937; Zbl 0016.35102)]
