Abstract

We consider a holographic description of the inflationary multiverse,according to which the wave function of the universe is interpreted asthe generating functional for a lower dimensional Euclidean theory. We analyze a simple model where transitions between inflationary vacuaoccur through bubble nucleation, and the inflating part of spacetimeconsists of de Sitter regions separated by thin bubble walls. In this model, we present some evidence that the dual theory is conformally invariant in the UV.
