Rzewuski sends a reprint on "differential structure of non-local theories".
Rzewuski, JanRzewuski encloses a note concerning conservation laws for non-local field theories.
Rzewuski, JanRosenfeld thanks Pauli for the letter and the typescript of Pauli's article on hidden parameters. He agrees with him and talks of his own article where the discussion of the problem will be put on philosophical ground.
Rosenfeld, LéonRosenfeld talks about Pauli's contribution to the forthcoming Bohr Festschrift.
Rosenfeld, LéonReichenbach refers to Pauli's article on hidden parameters. He expresses satisfaction at Pauli's strong rejection of this idea. He comments on the method of his argument against it.
Reichenbach, HansRayski replies to Pauli's letter of 4 February 1953. He talks about the commutation relations for non-local fields. He says that the problem reduces to the question of the existence of regular solutions.
Rayski, JarzyRayski sends another derivation of the commutation relations for a non-local theory, based on methods described by Schwinger.
Rayski, JarzyRasetti makes a short note about the history of the term "neutron" in the present sense of "neutrino".
Rasetti, Franco
