| Feb 27, 2017 at 5:07 | comment | added | YCor | "$Mod(\Sigma_g)$ cannot lift to $Diff(\Sigma_g)$" is not the same as "$Mod(\Sigma_g)$ cannot act by diffeomorphisms on that surface. What do you mean by the latter? I'm ready to believe that $Mod(\Sigma_g)$ has no injective homomorphism into $Homeo(S_{g'})$ for any $g'$, but I'm not sure you're claiming this. | |
