Gepner point and strong Bogomolov-Gieseker inequality for quintic
3-folds [PDF]
Yukinobu TodaWe propose a conjectural stronger version of Bogomolov-Gieseker inequality for stable sheaves on quintic 3-folds. Our conjecture is derived from an attempt to construct a Bridgeland stability condition on graded matrix factorizations, which should correspond to the Gepner point via mirror symmetry and Orlov equivalence. We prove our conjecture in the rank two case.View original: http://arxiv.org/abs/1305.0345
