Solving the Semiclassical Einstein Equation and a Moment Problem — •Daniel Siemssen — Universität Wuppertal, Wuppertal, Deutschland

I will present a novel approach towards solving the semiclassical Einstein equation in cosmological spacetimes. Different from previous approaches, this approach allows for arbitrary curvature coupling and full renormalization freedom. The method consists of two parts: 1) an infinite dimensional dynamical system, and 2) a moment problem.
