  Partial Derivatives in Noncommutative Spacetime

+ 2 like - 0 dislike
583 views

Will the order of taking partial derivatives matter in a noncommutative spacetime?

If so, what implications will that have on the way we do gauge theory? For example, will our Lagrangian now contain new terms which would normally cancel out in a commutative spacetime? An answer in the context of QFT or GR would be much appreciated.
