Normality in Uncountable Groups [PDF]
The main purpose of this paper is to describe the structure of uncountable groups of cardinality $\aleph$ in which all subgroups of cardinality $\aleph$ are normal.

Dimensional groups and fields [PDF]
We shall define a general notion of dimension, and study groups and rings whose interpretable sets carry such a dimensio. In particular, we deduce chain conditions for groups, definability results for fields and domains, and show that pseudofinite groups

Efficient quantum algorithms for some instances of the non-Abelian hidden subgroup problem [PDF]
In this paper we show that certain special cases of the hidden subgroup problem can be solved in polynomial time by a quantum algorithm. These special cases involve finding hidden normal subgroups of solvable groups and permutation groups, finding hidden

G-Groups and Biuniform Abelian Normal Subgroups [PDF]
We prove a weak form of the Krull-Schmidt Theorem concerning the behavior of direct-product decompositions of $G$-groups, biuniform abelian $G$-groups, $G$-semidirect products and the $G$-set $Hom(H,A)$. Here $G$ and $A$ are groups and $H$ is a $G$-group.

Some definition of the Artin exponent of finite groups [PDF]
The Artin exponent induced from cyclic subgroups of finite groups was studied extensively by T.Y. Lam. A Burnside ring theoretic version of Lam's results for $p$-groups was given by the author in an earlier paper.

On the number of subgroups of a given exponent in a finite abelian group [PDF]
This paper deals with the number of subgroups of a given exponent in a finite abelian group. Explicit formulas are obtained in the case of rank two and rank three abelian groups.

Maximal order Abelian Subgroups of Symmetric Groups [PDF]
In answer to a problem arising in the study of the statistical mechanics of systems of N quantum spins, the following classification of maximal order abelian subgroups G of \(S_ N\) is obtained. G is isomorphic to a direct product of k copies of \({\mathbb{Z}}_ 3\) if \(N=3k\). G is isomorphic to a direct product of \({\mathbb{Z}}_ 2\) with k copies of

Commutators in groups of piecewise projective homeomorphisms [PDF]
In 2012 Monod introduced examples of groups of piecewise projective homeomorphisms which are not amenable and which do not contain free subgroups, and later Lodha and Moore introduced examples of finitely presented groups with the same property.

Abelian subgroups of pro-$p$ Galois groups [PDF]
Summary: It is proved that non-trivial normal abelian subgroups of the Galois group of the maximal Galois \(p\)-extension of a field \(F\) (where \(p\) is an odd prime) arise from \(p\)-Henselian valuations with non-\(p\)-divisible value group, provided \(\# (\dot{F}/\dot{F}^{p})\geq p^{2}\) and \(F\) contains a primitive \(p\)-th root of unity.
