Peter Schupp (Bremen):
Noncommutative Gravity
Abstract:
Heuristic arguments suggest that the classical
picture of smooth commutative spacetime should be replaced by some kind of
quantum / noncommutative geometry at length scales and energies where quantum as well
as gravitational effects are important. Motivated by this idea much research has been
devoted to the study of quantum field theory on noncommutative spacetimes. More recently
the focus has started to shift back to gravity in this context. We give an introductory
overview to the formulation of general relativity in a noncommutative spacetime background
and discuss the possibility of exact solutions.
