Abstract
We consider generalized commutation relations in a dynamically evolving curved spacetime which, prior to some initial time and subsequent to some later time, is flat. By considering the Bogoliubov transformations associated with gravitationally induced particle creation, we find that the consistent evolution of the generalized commutation relations from the first flat region to the second flat region can only occur if q=±1.
