DESCRIPTION:Noncommutative geometry provides a representation of spacetime
  in terms of associative algebras of operators. The ultimate goal is to ar
 rive at a "quantum spacetime" that encodes quantum gravity effects at an e
 ffective level. Recently\, the characterization of 11 new quantum Minkowsk
 i spacetimes through their star algebras has been accomplished\, resulting
  in Lie-algebraic deformations of the standard Minkowski spacetime. The co
 nstruction of gauge theories on those noncommutative spacetimes has been i
 nvestigated. The starting point is the definition of a twisted differentia
 l calculus\, which can be achieved by considering multiderivations. Expres
 sion for a connection\, curvature\, and gauge transform can be found\, and
  asking for gauge invariance gives additional constraints on the theory.\n
