Quantum field theory on locally noncommutative spacetimes — •Gandalf Lechner1 and Stefan Waldmann21Institut für Theoretische Physik, Uni Leipzig — 2Leuven University

A class of spacetimes which are noncommutative only in a prescribed region is presented. These spacetimes are obtained by a generalization of Rieffel’s deformation procedure to deformations of locally convex algebras and modules by smooth polynomially bounded Rn-actions with compact support. Extending previous results of Bahns and Waldmann, it is shown how to perform such deformations in a strict sense. Some results on quantum fields propagating on locally noncommutative spacetimes are also given.
