## On the non-existence of regular stationary solutions of relativistic field equations

FIRST EDITION, OFFPRINT ISSUE of Einstein and Pauli’s only joint paper.

In 1940 Wolfgang Pauli left Europe to take a position at Princeton’s Institute for Advanced Study, where he remained until 1946. During his years at the IAS he enjoyed many scientific discussions with Einstein, out of which arose the present paper, their only joint effort. The paper “took up a problem that Einstein had investigated a few years earlier, namely that in the absence of matter... Einstein’s field equations under conditions to be specified should have the Euclidean metric as the only solution... Einstein’s and probably very strongly also Pauli’s motivation was the formal resemblance of the stationarity condition with the cylinder condition of the five-dimensional theory of Kaluza and Klein. The authors write: ‘When one tries to find a unified theory of the gravitational and electromagnetic fields, he cannot help felling that there is some truth in Kaluza’s five-dimensional theory’” (Enz, *No Time to be Brief: A Scientific Biography of Wolfgang Pauli*, p.388). Weil 211.
