We show that the complex saddle points of the no-boundary wave function with a positive cosmological constant and a positive scalar potential have a representation in which the geometry consists of a regular Euclidean AdS domain wall that makes a smooth transition to a Lorentzian, inflationary universe that is asymptotically deSitter. This leads to a dual formulation of the semiclassical no-boundary wave function ? and thus a concrete realization of a dS/CFT duality ? in terms of field theories on the final boundary that are certain relevant deformations of the CFTs that occur in AdS/CFT. The implications of this for the no-boundary measure in eternal inflation will be briefly discussed. |
