Hanno Gottschalk (Bonn):
Initial value formulation for the semicalssical Einstein equation on Robertson
Walker spacetimes
(joint work with B. Elzner)
The semiclassical Einstein Equation describes the coupling of a quantized field (fee
in this case) to classical gravity. Here we study a system that initially is in a
state with spatial isotropy and homogenity (Robertson Walker). We propose an
equation for an infinite dimensional dynamical system for this situation.
