Weak-field limit of Kaluza-Klein models with spherical compactification II: agreement with the observations
Weak-field limit Kaluza-Klein models spherical compactification agreement observations

We investigate the classical gravitational tests for the Kaluza-Klein model with spherical (of a radius $a$) compactification of the internal space. The model contains also a bare cosmological constan...

We investigate classical gravitational tests for the Kaluza-Klein model with spherical compactification of the internal two-dimensional space. In the case of the absence of a multidimensional bare cos...

We consider a six-dimensional braneworld model and we study the cosmological evolution of a (4+1) braneuniverse. Introducing matter on the brane we show that the scale factor of the physical three-dim...
