Feb 25, 2021 at 11:46 comment added Tobias Diez Thanks, indeed there was a $\lambda = 0$ missing.
Feb 25, 2021 at 10:58 comment added Nicolast Oh ok, I understand your notations and I think it is correct. At the end you mean "$H_A(Ad_\lambda P) = (gau(P)_A)_{\mathbb C}$ for $\lambda = 0$" right ? I was thinking of a polystable bundle, for which $\star F_A = \alpha \mathrm{Id}$ commutes with everyone, so that there is no non-zero eigenspace.
