dc.descriptionWe consider a cosmological model with a variable gravitational constant, G, based on a scalar-tensor theory. Using the recent observational data for the Hubble diagram of type Ia supernovae (SNeIa) we find a phenomenological expression describing the variation of G. The corresponding variation of the fine structure constant αwithin multidimensional theories is also computed and is shown not to support known constraints on Δα/ α.
