Jul 22, 2020 at 21:29 | comment | added | Willie Wong | Some people take $R_{ijkl} X^l = [\nabla_i, \nabla_j ]X_k$, some people define it to be the negative. I used in this computation the convention indicated in this comment, you are using the opposite one. So my version of the "Killing identity" is off from yours by a minus sign. | |

Jul 22, 2020 at 17:27 | comment | added | Spoilt Milk | Shouldn't the Riemann tensor terms be $R_{splm} + R_{smpl} + R_{slpm}$ so that using $R_{s[plm]} = 0$ would give the result mentioned? You have mentioned that your sign convention is different, but I don't get it. Could you please clarify this. Thanks for the answer. | |
