Twisted Covariance and Weyl Quantisation
Gherardo Piacitelli
文献摘要
In this letter we wish to clarify in which sense the tensor nature of the commutation relations [x^mu,x^nu]=i theta ^{mu nu} underlying Minkowski spacetime quantisation cannot be suppressed even in the twisted approach to Lorentz covariance. We then address the vexata quaestio “why theta”?
