Some considerations about cohomology of finite groups
(2013)
In this work we present some considerations about cohomology of finite groups. In the first part we use the restriction map in cohomology to obtain some results about subgroups of finite index in a group. In the second ...
Contributions to group work and to the management of collective processes in extension and rural development
(Elsevier, 2017-11)
Working with farmers´ groups, associations and cooperatives constitutes a fundamental element of extension work with family farmers. Despite the fact that extension practitioners face many problems in this area of their ...
On the Isometry Groups of Invariant Lorentzian Metrics on the Heisenberg Group
(Birkhauser Verlag Ag, 2014-01)
This work concerns the invariant Lorentzian metrics on the Heisenberg Lie group of dimension three H3(R) and the bi-invariant metrics on the solvable Lie groups of dimension four. We start with the indecomposable Lie groups ...
Free actions of abelian p-groups on the n-Torus
(2005-01-01)
In this work we make some contributions to the theory of actions of abelian p-groups on the n-Torus Tn. Set H ≅ ℤpk1 h1 × ℤpk2h2 × ⋯ × ℤpkrhr, r ≥ 1, k1 ≥ k2 ≥ ⋯ ≥ kr ≥ 1, p prime. Suppose that the group H acts freely on ...
The cohomological invariant E'(G,W) and some properties
(2012)
Let G be a group, W a nonempty G-set and M a Z2G-module. Consider the restriction map resG W : H1(G,M) → Pi wi∈E H1(Gwi,M), [f] → (resGG wi [f])i∈I , where E = {wi, i ∈ I} is a set of orbit representatives in W and Gwi = ...
On Polar Foliations and the Fundamental Group
(BIRKHAUSER VERLAG AG, 2011)
In this work we investigate the relation between the fundamental group of a complete Riemannian manifold M and the quotient between the Weyl group and reflection group of a polar action on M, as well as the relation between ...
Group work as a means of getting students to participate
(Universidad Nacional de Colombia, Facultad de Ciencias Humanas, 2000)
Three types of activities were worked on with a group of 15 shy and slow 10th grade students at the Centro Educativo Integral Colsubsidio to get them to participate and talk more often and fluently than they were doing. ...
