The square of that operator is plus one for integral spin and minus one for half-integral spin.
A simplification of the Frobenius criterion on space groups that gives the degeneracies that double under this statement's corresponding operator is named for Herring. The square of that operator is plus one for integral spin and minus one for half-integral spin. A criterion given by Wolfenstein for this property was applied by Sehgal and van Leusen to analyze CPLEAR, an experiment at CERN that showed a difference between the rates of antikaon to kaon transitions and kaon to antikaon transitions. Loschmidt's paradox concerns its violation in the molecular chaos assumption of Boltzmann's H-theorem. Noether's theorem relates this property to energy conservation. A theorem which would be violated were neutrons to have nonzero electric dipole moment holds that the product of this property with charge conjugation and parity is always preserved. Applying that to a black hole gives a white hole. For 10 points, name statemen, whose corresponding operator would cause events to happen backwards.
