Stability conditions on Fano threefolds of Picard number one
Abstract
We prove the conjectural Bogomolov-Gieseker type inequality for tilt slope stable objects on each Fano threefold X of Picard number one. Based on the previous works on Bridgeland stability conditions, this induces an open subset of geometric stability conditions on Db(X). We also get a new stronger bound for the Chern characters of slope semistable sheaves on X.
