    1990, Jurg Frohlich, Quantum Statistics and Locality, D. G. Caldi, George D. Mostow (editors), Proceedings of the Gibbs Symposium: Yale University, May 15-17, 1989, American Mathematical Society, American Institute of Physics, page 93, A choice of particle statistics in quantum mechanics is equivalent to choosing representations Uₙ, of π₁(Mₙ), for all n, in the quantization procedure described in §1.2; see (1.3). Thus, for a system of point particles in d > 3 dimensional, physical space, particle statistics is described by the symmetry character of wave functions under permutations of particle positions.
