Time variation of fundamental constants in nonstandard cosmological models
(American Physical Society, 2017-10)
In this work we have studied the lithium problem in nonstandard cosmological models. In particular, by using the public code alterbbn, we have included in the computation of the primordial light nuclei abundances, the ...
Primordial Nucleosynthesis with Varying Fundamental Constants: A Semianalytical Approach
(IOP Publishing, 2006-01)
Using the semi-analytic method proposed by Esmaizaldeh and coworkers we calculate the abundances of the light elements produced during primordial nucleosynthesis assuming that the gauge coupling constants of the fundamental ...

The fundamental progroupoid of a general topos
(Elsevier Science, 2008-11)
It is well known that the category of covering projections (that is, locally constant objects) of a locally connected topos is equivalent to the classifying topos of a strict progroupoid (or, equivalently, a localic ...

(Pontificia Universidad Católica Argentina. Facultad de Ciencias Sociales. Departamento de Historia, 2021-12)
A partir de la ponderación realizada por Constant de la libertad ateniense como precursora del moderno espíritu liberal, el siguiente artículo se propone establecer una serie de interpretaciones acerca de lo que por ello ...
Helium and deuterium abundances as a test for the time variation of the fine structure constant and the Higgs vacuum expectation value
(IOP Publishing, 2007-12)
We use the semi-analytic method of Esmailzadeh et al (1991 Astrophys. J. 378 504-18) to calculate the abundances of helium and deuterium produced during Big Bang nucleosynthesis assuming the fine structure constant and the ...
