Averaged Gravity — •Juliane Behrend — Institut für Theoretische Physik, Universität Ulm

The fact that an adequate description of gravitational dynamics on cosmological scales should be given by an average over Einstein's equations is currently receiving considerable attention. Finding an accurate theory of averaged gravity is difficult since we lack a suitable averaging procedure for tensor quantities in general relativity. In this talk I will discuss in depth various approaches to such a procedure and address remaining problems that need to be overcome to find a viable averaged theory.
