Maths HEP Lunchtime Seminars: Cosmological and Black String solutions in Brane-World Models
14 November 2003 13:00 in CM221
"The introduction of extra, spacelike dimensions has led to the formulation of the so-called brane-world models in which a 3-brane plays the role of our 4-dimensional spacetime embedded in a higher dimensional, flat or Anti de Sitter manifold. Any black hole or cosmological solution must follow from the higher-dimensional Einstein's equations and they are almost certain to be different from the usual 4-dimensional ones. We will discuss implications both on the cosmology and black-hole physics in this type of models, and address questions regarding the restoration of the Friedmann cosmology on the brane, the stabilization of the size of extra dimensions, the localization of black hole solutions near the brane and the regularity of the higher-dimensional spacetime."
