| Dec 10, 2021 at 17:24 | comment | added | kryomaxim | I mean derivatives of delta functions where as an argument a group is passed. | |
| Dec 10, 2021 at 17:12 | comment | added | paul garrett | Of course, general derivatives of $\delta$ are not conjugation-invariant... but, for example, $\Omega^k\delta$, with $\Omega$ the Casimir operator, have such expressions. Otherwise I don't see anything better than your natural derivative expressions. Can you clarify? | |
