Sažetak:

We elaborate on the role of quantum statistics in twisted Poincare invariant
theories. It is shown that, in order to have twisted Poincare group as the
symmetry of a quantum theory in Moyal space, statistics must be twisted. It is
also confirmed that the removal of UV-IR mixing (in the absence of gauge
fields) in such theories is a natural consequence. We also present a novel way
of imposing gauge invariance in such spaces and consider NCQED.
