Teleparallel Gravity in Five Dimensional Theories

Understand

We study teleparallel gravity in five-dimensional spacetime with particular discussions on Kaluza-Klein (KK) and braneworld theories.

• We directly perform the dimensional reduction by differential forms.
• In the braneworld theory, the teleparallel gravity formalism in the Friedmann-Lema\^{i}tre-Robertson-Walker cosmology is equivalent to GR due to the same Friedmann equation, whereas in the KK case the reduction of our formulation does not recover the effect as GR of 4-dimensional spacetime.
