| Apr 10, 2020 at 15:28 | comment | added | YCor | I'd be curious whether considering conjugation in $\mathrm{MCG}^+$ (group of oriented self-diffeotopies) is equivalent to conjugation (of elements of $\mathrm{MCG}^+$) in $\mathrm{MCG}^\pm$ (the group of all self-diffeotopies, which is also $\mathrm{Out}(\Gamma_g)$ for a closed surface of genus $g$). For instance this fails in the $2$-torus, since a non-trivial unipotent matrix is conjugate to its inverse in $\mathrm{GL}_2(\mathbf{Z})$, but not in $\mathrm{SL}_2(\mathbf{Z})$. | |
