| Dec 5, 2022 at 13:26 | comment | added | Sasha | Which semistability you are interested in? | |
| Dec 5, 2022 at 13:15 | comment | added | LAPRAS | If we consider the sheaf $(\pi^*(i_*E))/Tor$, then can we say about its semistability ? | |
| Dec 5, 2022 at 10:30 | comment | added | Sasha | Even in this case. | |
| Dec 5, 2022 at 10:22 | comment | added | LAPRAS | What about if $E$ is itself locally free on $X^s$ and $X$ is normal ? | |
| Dec 5, 2022 at 10:03 | comment | added | Sasha | In many cases the sheaf $\pi^*(i_*E)$ is even not torsion free. | |
