Identities of conformal algebras and pseudoalgebras

Pavel Kolesnikov

For a given conformal algebra , we write down the correspondence between identities of the coefficient algebra $\Coeff C$ and identities of itself as of pseudoalgebra. In pa…

Extending representations of braid groups to the automorphism groups of free groups

Valerij G. Bardakov

We construct a linear representation of the group IA(F_n) of IA-automorphisms of a free group F_n, an extension of the Gassner representation of the pure braid group P_n. Although…

The virtual and universal braids

Valerij G. Bardakov

We study the structure of the virtual braid group. It is shown that the virtual braid group is a semi--direct product of the virtual pure braid group and the symmetric group. Also,…

On -separability of subgroups of free metabelian groups

Valerij G. Bardakov

We prove that every free metabelian non--cyclic group has a finitely generated isolated subgroup which is not separable in the class of nilpotent groups. As a corollary we prove th…

Counting conjugacy classes of subgroups in a finitely generated group

A. D. Mednykh

A new general formula for the number of conjugacy classes of subgroups of given index in a finitely generated group is obtained.

On the conjugacy problem for cyclic extensions of free groups

Valerij Bardakov, Leonid Bokut, Andrei Vesnin

We study the conjugacy problem in cyclic extensions of free groups. It is shown that the conjugacy problem is solvable in split extensions of finitely generated free groups by virt…
