The Universe Dynamics from Topological Considerations

Understand

We explore the possibility that the dynamics of the universe can be reproduced choosing appropriately the initial global topology of the Universe.

• In this work we start with two concentric spherical three-dimensional branes S^3, with radius a_1<a_2 immersed in a five-dimensional space-time.
• The novel feature of this model is that in the interior brane there exist only spin-zero fundamental fields (scalar fields), while in the exterior one there exist only spin-one fundamental interactions.
• As usual, the bulk of the universe is dominated by gravitational interactions.
