The -Noncommutative Minimal Model Program
Dongjian Wu, Nantao Zhang
In this paper, we study the -equivariant noncommutative minimal model program (-NMMP), as an equivariant generalization of the framework introduced in arXiv:2301.13168. The a…
Ore extensions of multiplier Hopf coquasigroups
Rui Zhang, Na Zhang, Yapeng Zeng +1
In this paper, Ore extensions of multiplier Hopf coquasigroups are studied. Necessary and sufficient conditions for the Ore extension of a regular multiplier Hopf coquasigroup to b…
Stability conditions on blowups
Nantao Zhang
We study the relation between perverse stability conditions and geometric stability conditions under blow up. We confirm a conjecture of Toda in some special cases and show that ge…
Stability Conditions on
Dongjian Wu, Nantao Zhang
We construct a subset of the space of stability conditions for any projective threefold with an ample polarization that satisfies a certain Bogomolov-Gieseker inequality to refine…
