Abstract
BERMAN, Marcelo Samuel. Simple Model with Time-Varying Fine-Structure "Constant". Rev. mex. astron. astrofis [online]. 2009, vol.45, n.2, pp.139-142. ISSN 0185-1101.
Extending the original version written in colaboration with L.A. Trevisan, we study the generalisation of Dirac's LNH, so that time-variation of the fine-structure constant, due to varying electrical and magnetic permittivities is included along with other variations (cosmological and gravitational "constants"), etc. We consider the present Universe, and also an inflationary scenario. Rotation of the Universe is a given possibility in this model.
Keywords : cosmology: theory.
