| Jun 1, 2020 at 14:36 | comment | added | Johan | Thank you! It actually seems like the same argument also works for the coarse moduli space of semi-stable Higgs bundles, no? Also, flatness should be true as well for the Hitchin fibration on the moduli space of Higgs bundles that take value in a line bundle other than the canonical bundle (one more positive). The symplectic context is missing in that set-up. Would it be possible to prove the key result (Prop. 8 in Ginzburg) without Lemma 7 (the fact that the stack of globally nilpotent Higgs bundles is isotropic)? | |
