| Apr 20, 2021 at 10:37 | comment | added | Martin Gisser | Carlo Beenakker: Yes, that's what I'm looking for. Something after Einstein's 1916 paper. Before that he (and Grossmann) were inconsistent, naturally, as they were figuring out the maths and notation. The 1916 paper is not just a milestone in physics, but also in tensor calculus (mixed tensors). So there should be some very good reason for dropping Einstein's minus and making things (a little) messier. | |
| Apr 20, 2021 at 8:25 | comment | added | Carlo Beenakker | it might be helpful if you could indicate what kind of answer you are looking for; a paper that says "we choose a different sign from Einstein for this or that reason" and which was so influential that later users followed it? Since Einstein himself was not consistent in the choice of the sign, I doubt that such a paper exists (although there are many sources that noted that the identification of minus the second Christoffel symbol with the gravitational field is mistaken, obviating the need for the minus sign) | |

| Mar 26, 2021 at 2:35 | comment | added | Martin Gisser | I guess the culprit is Hermann Weyl. In Space Time Matter he introduces "The Conception of Affine Relationship" with a superfluous minus in the very first formula (33) p.112. I haven't yet comprehended his next page ... I guess his motive is to get the "right" sign for the curvature tensor... | |
