Simple Model with Time-Varying Fine-Structure "Constant''

Marcelo Samuel Berman

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 ne-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 in ationary scenario. Rotation of the Universe is a given possibility in this model.
