Letter from W. Pauli to Teubner Verlagsgesellschaft. Related to the republication of "The theory of relativity".

Copy and corrections of a speech held at Geneva by Heisenberg, copy sent to Pauli.

Answer to a letter from H. Kita where he pointed out a mathematical mistake in one of Heisenberg's calculations for a book or an article. See also 1/463 and 1/532.

Heisenberg is happy to see that he and Källén agree on some mathematical points (S-Matrix, Hilbertraum I, Lee-Model).
