M. Chaichian et al., Q-SUPERSYMMETRIC GENERALIZATION OF VON-NEUMANN THEOREM, Journal of physics. A, mathematical and general, 26(18), 1993, pp. 909-917
Assuming that there exist operators which form an irreducible represen
tation of the q-superoscillator algebra, it is proved that any two suc
h representations are equivalent, related by a uniquely determined sup
erunitary transformation. This provides a q-supersymmetric generalizat
ion of the well known uniqueness theorem of von Neumann for any finite
number of degrees of freedom.
