We give a local existence and uniqueness theorem for solutions of Einstein’s equations with dust energy momentum tensor in the class of m -dimensional, analytic, transverse, signature type changing spacetimes where the initial conditions are give

Signature (type) changing spacetimes are the classical limit of a variant of the no-boundary proposal of Hartle and Hawking (1983). I study spacetimes where the Einstein equation is coupled to a scalar field and give a heuristic, semiclassical argume

There exists a widespread belief that signature type change could be used to avoid spacetime singularities. We show that signature change cannot be utilised to this end unless the Einstein equation is abandoned at the suface of signature type change.
