On Undecidability of Finite Subsets Theory for Torsion Abelian Groups
Let M be a commutative cancellative monoid with an element of infinite order. The binary operation can be extended to all finite subsets of M by the pointwise definition. So, we can consider the theory of finite subsets of M.

Determine the value d(M(G)) for non-abelian p-groups of order q = pnk of Nilpotency c
In this paper we prove that if n, k and t be positive integer numbers such that t < k < n and G is a non abelian p-group of order pnk with derived subgroup of order pkt and nilpotency class c, then the minimal number of generators of G is at most p1 2 (

How SU(2)$_4$ Anyons are Z$_3$ Parafermions
We consider the braid group representation which describes the non-abelian braiding statistics of the spin $1/2$ particle world lines of an SU(2)$_4$ Chern-Simons theory.

On the structure of finite groups associated to regular non-centralizer graphs
The non-centralizer graph of a finite group $ G $ is the simple graph $ \Upsilon_G $ whose vertices are the elements of $ G $ with two vertices are adjacent if their centralizers are distinct.

Rigid automorphisms of linking systems
A rigid automorphism of a linking system is an automorphism that restricts to the identity on the Sylow subgroup. A rigid inner automorphism is conjugation by an element in the center of the Sylow subgroup.

Elementary Properties of Ordered Abelian Groups [PDF]
Introduction. A complete classification of abelian groups by their elementary properties (i.e. properties that can be formalized in the lower predicate calculus) was given by Szmielew [9]. No such attempt, however, has so far been made with respect to ordered groups.

Elementary abelian groups of rank 5 are DCI-groups [PDF]
In this paper, we show that the group $\mathbb{Z}_p^5$ is a DCI-group for any odd prime $p,$ that is, two Cayley digraphs Cay$(\mathbb{Z}_p^5,S)$ and Cay$(\mathbb{Z}_p^5,T)$ are isomorphic if and only if $S=T^ $ for some automorphism $ $ of the group $\mathbb{Z}_p^5$.

A remark on elementary abelian groups [PDF]
Dr M.F. Newman has asked whether in the absence of the Axiom of Choice it is possible to have two non-isomorphic elementary abelian groups of the same (finite) exponent and of the same (infinite) cardinality. By means of an example, I show that this is in fact possible, if the exponent is at least five; I do not know the answer in the remaining two ...

Elementary Extensions of Linear Topological Abelian Groups [PDF]
R. MacDowell and E. Specker obtain a structure theorem for elementary extensions of the integers by considering a certain residue mapping. In this paper we characterize those abelian groups in which an analogous situation exists and obtain the MacDowell-Specker result as a special case of our theory.

On finite $p$-groups with abelian automorphism group [PDF]
We construct, for the first time, various types of specific non-special finite $p$-groups having abelian automorphism group. More specifically, we construct groups $G$ with abelian automorphism group such that $\gamma_2(G) < \mathrm{Z}(G) < \Phi(G)$, where $\gamma_2(G)$, $\mathrm{Z}(G)$ and $\Phi(G)$ denote the commutator subgroup, the center and the ...
