| « Gravity dynamics in braneworlds with conical internal space » |
|
A. Papazoglou |
| We will discuss the status of braneworld models with two internal dimensions and specifically the ones where the internal space has conical structure. One of the motivations for studding such models is that they could be useful towards the resolution of the cosmological constant problem. We will discuss the problem of describing gravity dynamics on them and present a specific regularization which makes this possible. We will analyze a simple scenario where a cosmological evolution is induced in the regularized brane due to its motion in the internal space. |
