- Holographic description of cosmological singularity

In my talk I will discuss our recent paper

hep-th/1211.1322 where we construct a 3D conformal field theory dual to

asymptotically AdS cosmology in four dimensions. Due to the scale invariance

this dual theory allows an infinite family of instantons each of which breaks

the conformal group O(3,2) down to O(3,1). These instantons are dual to bulk

instantons responsible for nucleating an O(3,1) invariant cosmological

bubble. Presumably they indicate an

infinite instability rate, however we are able to sum over all of them

completely. The resulting theory is manifestly stable, unitary and finite.
