Fivel %J Physics %D 1994 %I arXiv %X It is shown that the algebraic structure of finite Heisenberg groups associated with the tensor product of two Hilbert spaces leads to a simple demonstration valid in all Hilbert space dimensions of the impossibility of non-contextual hidden variables. %U http://arxiv.org/abs/hep-th/9409149v1
