How can you treat a noncommutative model of space-time

  1. as a physicist i know how to define the concepts such as derivatives integrals and so on, the problem comes when one has a noncommutative space so [tex] [x_a , x_b ] = \theta _{ab} [/tex] how can you define an area or Volume ?? or also , in case space is noncommutative do divergences dissapear ?
