| Sep 29, 2020 at 10:56 | comment | added | Christoph Weis | Thank you very much for your answer! You have convinced me that it is enough to treat the discrete and simply-connected case. However, I had another try at tracing through the proof for $A=\mathbb{R}$ mentioned in my post. It is not obvious to me that this generalises to simply connected $A$. Do you have a reference for this claim? | |
