Cosmologies with Null Singularities and their Gauge Theory Duals
Sumit R. Das, Jeremy Michelson, K. Narayan +1
We investigate backgrounds of Type IIB string theory with null singularities and their duals proposed in hep-th/0602107. The dual theory is a deformed N=4 Yang-Mills theory in 3+1…

Phases of unstable conifolds
K. Narayan
We explore the phase structure induced by closed string tachyon condensation of toric nonsupersymmetric conifold-like singularities described by an integral charge matrix $Q=(n_1 n…

Time Dependent Cosmologies and Their Duals
Sumit R. Das, Jeremy Michelson, K. Narayan +1
We construct a family of solutions in IIB supergravity theory. These are time dependent or depend on a light-like coordinate and can be thought of as deformations of AdS_5 x S^5. S…
