Koszul configurations of points in projective spaces
Alexander Polishchuk
We prove a new criterion for the homogeneous coordinate ring of a finite set of points in to be Koszul. Like the well known criterion due to Kempf it involves only inc…

Holomorphic bundles on 2-dimensional noncommutative toric orbifolds
Alexander Polishchuk
We define the notion of a holomorphic bundle on the noncommutative toric orbifold associated with an action of a finite cyclic group on an irrational rotation algebra.…

Universal triple Massey products on elliptic curves and Hecke's indefinite theta series
Vicentiu Pasol, Alexander Polishchuk
Generalizing math.AG/0003076 we express universal triple Massey products between line bundles on elliptic curves in terms of Hecke's indefinite theta series. We show that all Hecke…
