Exactness and Effective Degree Bound of Lasserre's Relaxation for Polynomial Optimization over Finite Variety
Zheng Hua, Zheng Qu
In this paper, we address the effective degree bound problem for Lasserre's hierarchy of moment-sum-of-squares (SOS) relaxations in polynomial optimization involving variables.…
Quivers with analytic potentials
Zheng Hua, Bernhard Keller
Given a quiver , a formal potential is called analytic if its coefficients are bounded by the terms of a geometric series. As shown by Toda, the potentials appearing in the defo…
On the Grothendieck groups of toric stacks
Zheng Hua
In this note, we prove that the Grothendieck group of a smooth complete toric Deligne-Mumford stack is torsion free. This statement holds when the generic point is stacky. We also…
On the conjecture of King for smooth toric Deligne-Mumford stacks
Lev Borisov, Zheng Hua
We construct full strong exceptional collections of line bundles on smooth toric Fano Deligne-Mumford stacks of Picard number at most two and of any Picard number in dimension two.…
On Calabi-Yau threefolds with large nonabelian fundamental groups
Lev Borisov, Zheng Hua
In this short note we construct Calabi-Yau threefolds with nonabelian fundamental groups of order 64 as quotients of the small resolutions of certain complete intersections of quad…
