Did the Pseudo-Sphere Universe have a Beginning?

Abstract

A calculation of the no-boundary wave-function of the universe is put forward for a spacetime with negative curvature. A semi-classical Robertson-Walker approximation is attempted and two solutions to the field equations, one Lorentzian and the other a tunneling one are found. The regularity of those solutions are analysed explicitly, both in 2+1 and 3+1 dimensions and a conical singularity is found at the origin of the time axis, contradicting the no-boundary assumption.
