Title: Noncommutative Friedmann-Walker spacetimes, quantum field theory and the Einstein equations
Abstract: In this talk I will report on recent progress on the extension of DFR quantum field theory on noncommutative Minkowski spacetime to the case of arbitrary expanding flat Friedmann-Walker spacetimes. These allow to make sense of a noncommutative version of Friedmann equations whose solution is in turn expected to determine the precise form of the spacetime commutation relations.
