A group topology on the free abelian group of cardinality c that makes its square countably compact
(POLISH ACAD SCIENCES INST MATHEMATICS, 2011)
Under p = c, we prove that it is possible to endow the free abelian group of cardinality c with a group topology that makes its square countably compact. This answers a question posed by Madariaga-Garcia and Tomita and by ...
Independent finite automata on Cayley graphs
(Springer, 2017)
In the setting of symbolic dynamics on discrete finitely generated infinite groups, we define a model of finite automata with multiple independent heads that walk on Cayley graphs, called group-walking automata, and use ...

Generalized Gottlieb and whitehead center groups of space forms
(2019-01-01)
We extend Oprea's result that the Gottlieb group G1(S2n+1/H) is ZH (the center of H) and show that for a map f: A → S2n+1/H, under some conditions on A, we have G1 f (S2n+1/H) = ZHf*(π1(A)), the centralizer of the image ...
CENTRAL UNITS IN METACYCLIC INTEGRAL GROUP RINGS
(TAYLOR & FRANCIS INC, 2008)
In this article, we give a method to compute the rank of the subgroup of central units of ZG, for a finite metacyclic group, G, by means of Q-classes and R-classes. Then we construct a multiplicatively independent set u ...
The domino problem on groups of polynomial growth
(European Mathematical Society, 2018)
We conjecture that a finitely generated group has a decidable domino problem if and only if it is virtually free. We show this is true for all virtually nilpotent finitely generated groups (or, equivalently, groups of ...
Toward a group empowerment model in mexican organizations : A structural equation modeling approach
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2005-01-01)
A model of group empowerment within the context of Mexican organization is proposed and empirically tested. Studying groups in the workplace has attracted increasing attention during the last years from academics and ...
