نویسنده
چکیده
A relatively recent study by Mars and Senovilla provided us with a uniqueness result for the exterior vacuum gravitational field of global models describing finite isolated rotating bodies in equilibrium in General Relativity (GR). The generalisation to exterior electrovacuum gravitational fields, to include charged rotating objects, is presented here.

We study the exterior vacuum problem for first and second order stationary and axially symmetric perturbations of static bodies. The boundary conditions and their compatibility for the existence of an asymptotically flat exterior solution are discussed.

We find the general solution for the spacetimes describing the interior of static black holes with an equation of state of the type T 0 0 = T 1 1 (T being the stress-energy tensor). This form is the one expected from taking into account different quantum effects associated with strong gravitational fields. We recover all the particular examples found in the literature. We remark that all the so...

We derive formulae for the time variation of the gravitational " constant " and of the fine structure " constant " in various models with extra dimensions and analyze their consistency with the observational data.
