Jul 5, 2016 at 3:18 | comment | added | Malkoun | For 1, compute $dg$, which is a 2 by 2 matrix of $1$-forms. Then compute dg†, which is also a 2 by 2 matrix of $1$-forms. After that, take the matrix product dg†dg, which is a 2 by 2 matrix of $(0,2)$ forms (by a $(0,2)$ form I mean a sum of tensor products of $1$-forms, i.e. a section of $T^* \otimes T^*$), and then take the trace. | |

Jul 5, 2016 at 1:29 | comment | added | Selene Routley | Do you have any Lie theoretical background? You don't need it to write out the expressions, but it would help me give some hints without writing it out in full (time is tight this morning!) You're essentially working out what the Killing form becomes when you translate your tangent space away from the tangent to the identity to the tangent to another group member. | |
