摘要
The global dimension function introduced by Qiu is a generalization of global homological dimension for abelian category. The flow via global dimension function has been used to prove contractibilty of some stability spaces. In this talk, I will explain recent work with Dongjian Wu, showing an explicit subset of geometric stability condition of some projective threefolds including $\mathbb{P}^3$ has global dimension 3 as expected. Our proof uses generalized Bogomolov inequality as key ingredient.
