Kiritsis, Elias Holography and brane-bulk energy exchange. (English) Zbl 1236.83014 J. Cosmol. Astropart. Phys. 2005, No. 10, Paper No. 014, 35p. (2005). Summary: Holography relates the low energy regime of the five-dimensional description of generalized Randall-Sundrum cosmology to a four-dimensional theory. The four-dimensional theory describes observable matter interacting with a hidden (non-conformal) gauge theory. This provides a new arena for implementing the cosmological brane-bulk energy exchange processes studied previously. Unlike the five-dimensional description, there is no big-bang singularity in four dimensions. Some simple solutions are presented in four dimensions. A gauge theory description of observable four-dimensional gravity is also advocated.
