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.
