Cosmological solutions from induced matter model applied to 5D f(R,T) gravity and the shrinking of the extra coordinate

In this work, I present exact cosmological solutions from Wesson’s induced matter model applied to a general 5D metric in f ( R , T ) theory of gravity. The non-conservation of the energy-momentum tensor, predicted by f ( R , T ) theory, allows the derivation of a relation that describes the time ev...

Description
Summary:In this work, I present exact cosmological solutions from Wesson’s induced matter model applied to a general 5D metric in f ( R , T ) theory of gravity. The non-conservation of the energy-momentum tensor, predicted by f ( R , T ) theory, allows the derivation of a relation that describes the time evolution of the extra coordinate, revealing its compactification. It is shown that such a compactification could induce the effects of an accelerated expansion in the observable universe.
