RESUMEN
]]> Como una extensión del trabajo publicado con L.A. Trevisan, estudiamos la generalización de la LNH de Dirac, de tal manera que la variación en el tiempo de la constante de la estructura fina debida a variaciones en la permitividad eléctrica y magnética queda incluida al igual que otras variaciones (las "constantes" gravitatoria y cosmológica, etc.). Consideramos el Universo presente y también un escenario inflacionario. La rotación del Universo puede considerarse en el modelo.
ABSTRACT
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.
Key Words: cosmology: theory.
