Semiclassical effects and the onset of inflation

We present a class of exact spherically symmetric solutions to the constraint equations of general relativity coupled to a Klein-Gordon field. We analyze the subsequent evolution of the consistent Cauchy data represented by those solutions, showing that only certain special initial conditions eventu...
