The central subgroup of the nonabelian tensor square of a torsion free space group [PDF]

open access: yesAIP Conference Proceedings, 2016
Space groups of a crystal expound its symmetry properties. One of the symmetry properties is the central subgroup of the nonabelian tensor square of a group. It is a normal subgroup of the group which can be ascertained by finding the abelianisation of the group and the nonabelian tensor square of the abelianisation group.

Isometries of Lipschitz‐free Banach spaces [PDF]

open access: yesJournal of the London Mathematical Society, Volume 110, Issue 5, November 2024.
Abstract We describe surjective linear isometries and linear isometry groups of a large class of Lipschitz‐free spaces that includes, for example, Lipschitz‐free spaces over any graph. We define the notion of a Lipschitz‐free rigid metric space whose Lipschitz‐free space only admits surjective linear isometries coming from surjective dilations (i.e ...

Intersection configurations in free and free times free-abelian groups [PDF]

open access: yes, 2023
In this paper we study intersection configurations -- which describe the behaviour of multiple (finite) intersections of subgroups with respect to finite generability -- in the realm of free and free times free-abelian (FTFA) groups.

A REFINED WARING PROBLEM FOR FINITE SIMPLE GROUPS

open access: yesForum of Mathematics, Sigma, 2015
Let $w_{1}$ and $w_{2}$ be nontrivial words in free groups $F_{n_{1}}$ and $F_{n_{2}}$, respectively. We prove that, for all sufficiently large finite nonabelian simple groups $G$, there exist subsets $C_{1}\subseteq w_{1}(G)$ and $C_{2}\subseteq w_{2}(G)

Zero Entropy Is Generic

open access: yesEntropy, 2016
Dan Rudolph showed that for an amenable group, Γ, the generic measure-preserving action of Γ on a Lebesgue space has zero entropy. Here, this is extended to nonamenable groups.

The central subgroups of the nonabelian tensor squares of some bieberbach groups with elementary Abelian 2-group point group [PDF]

open access: yes, 2017
Bieberbach groups are torsion free crystallographic groups. In this paper, our focus is on the Bieberbach groups with elementary abelian 2-group point group, 2 2 C C? . The central subgroup of the nonabelian tensor square of a group G is generated by g g

A nonabelian Brunn-Minkowski inequality [PDF]

open access: yes, 2023
Henstock and Macbeath asked in 1953 whether the Brunn-Minkowski inequality can be generalized to nonabelian locally compact groups; questions along the same line were also asked by Hrushovski, McCrudden, and Tao.

Constructions of large translation nets with nonabelian translation groups [PDF]

open access: yes, 2008
In this paper the first infinite series of translation nets with nonabelian translation groups and a large number of parallel classes are constructed. For that purpose we investigate partial congruence partitions (PCPs) with at least one normal component.

Strongly dense free subgroups of semisimple algebraic groups II [PDF]

open access: yes, 2023
It was shown in [9] that there exist strongly dense free subgroups in any semisimple algebraic group over a large enough field. These are nonabelian free subgroups all of whose subgroups are either cyclic or Zariski-dense.
