A note on restriction theorems for semistable sheaves
arXiv:0905.4606 · doi:10.4310/MRL.2010.v17.n5.a2
Abstract
We prove a new restriction theorem for semistable sheaves on varieties in all characteristics strengthening previous results. We also prove restriction theorem for strong semistability for varieties with some non-negativity constrains on the cotangent bundle (e.g., most of Fano and Calabi-Yau varieties).
