Completeness properties of locally quasi-convex groups
It is natural to extend the Grothendieck theorem on completeness, valid for locally convex topological vector spaces, to Abelian topological groups. The adequate framework to do it seems to be the class of locally quasi-convex groups. However, in this paper we present examples of metrizable locally quasi-convex groups for which the analogue to the ...

Local homology properties of boundaries of groups.
Let \(\widetilde X\) be a Euclidean retract, ER (embeddable in some Euclidean space as a retract). A closed subset \(Z\) of \(\widetilde X\) is a \(Z\)-set if there is deformation \(h_t\): \(\widetilde X\to \widetilde X\) with \(h_0= \text{id}\) and \(h_t(\widetilde X) \cap Z= \emptyset\) for \(t>0\) (two equivalent definitions are given).

Some properties of locally compact groups [PDF]
In this paper a number of questions about locally compact groups are studied. The structure of finite dimensional connected locally compact groups is investigated, and a fairly simple representation of such groups is obtained. Using this it is proved that finite dimensional arcwise connected locally compact groups are Lie groups, and that in general ...

Bimodule properties of group-valued local fields and quantum-group difference equations [PDF]
We give an explicit construction of the quantum-group generators ---local, semi-local, and global --- in terms of the group-valued quantum fields $\tilde g$ and $\tilde g^{-1}$ in the Wess-Zumino-Novikov-Witten (WZNW) theory. The algebras among the generators and the fields make concrete and clear the bi-module properties of the $\tilde g$ and the ...

Ergodic Properties of Automorphisms of a Locally Compact Group [PDF]
The following remark is made by Halmos in his book [2, p. 29]. "Can an automorphism of a locally compact but noncompact group be an ergodic measure preserving transformation? Nothing is known about this subject. Only in the compact case has anything ever been done." The aim of this paper is to give an answer to this question of Halmos.

On Local Embedding Properties of Injectors of Finite Soluble Groups [PDF]
AbstractIn the present paper we consider Fitting classes of finite soluble groups which locally satisfy additional conditions related to the behaviour of their injectors. More precisely, we study Fitting classes 1 ≠⊆such that an-injector of G is, respectively, a normal, (sub)modular, normally embedded, system permutable subgroup of G for all G ...

A Trio of New Local Group Galaxies with Extreme Properties [PDF]
We report on the discovery of three new dwarf galaxies in the Local Group. These galaxies are found in new CFHT/MegaPrime g,i imaging of the south-western quadrant of M31, extending our extant survey area to include the majority of the southern hemisphere of M31's halo out to 150 kpc.

Some residual properties of locally nilpotent groups
Abstract We prove that locally nilpotent linear groups are divisible by residually-periodic and actually enjoy various stronger properties. Examples severely restrict the possibilities for generalizations, but we do extend our results from linear groups to groups of automorphisms of both Noetherian modules and Artinian modules over commutative rings.

Some properties of locally quasi-convex groups
The author considers an analog of convexity for topological groups defined by N. Vilenkin in 1951 as follows. A subset \(S\) of a topological group \(G\) is called quasi-convex if for every \(x\in G\backslash S\) there exists a continuous character \(\chi: G\to \mathbb{T}\) such that \(\text{Re} \chi (x)
