On a Lorentz-invariant interpretation of noncommutative space–time and its implications on noncommutative QFT

By invoking the concept of twisted Poincaré symmetry of the algebra of functions on a Minkowski space–time, we demonstrate that the noncommutative space–time with the commutation relations [xμ,xν]=iθμν, where θμν is a constant real antisymmetric matrix, can be interpreted in a Lorentz-invariant way....
