    "abstract": "The method of transfer functions is developed as a tool for studying Bell\ninequalities, alternative quantum theories and the associated physical\nproperties of quantum systems. Non-negative probabilities for transfer\nfunctions result in Bell-type inequalities. The method is used to show that all\nrealistic Lorentz-invariant quantum theories, which give unique results and\nhave no preferred frame, can be ruled out on the grounds that they lead to weak\nbackward causality.",
