Gauge Duals of some Singularities
Speaker(s): Sumit Das
Abstract: Certain classes of cosmological backgrounds in asymptotically anti-de-Sitter space-times have hologropically dual descriptions in terms of gauge theories. We analyse such backgrounds with smooth initial conditions, where curvatures become strong in a finite time and the gravity equations break down. We will show how the dual gauge theory can be used to continue time evolution in this singular region and speculate on the nature of space-time at late times.
