The -structure on the derived endomorphism algebra of the unit in a monoidal category
Wendy Lowen, Michel Van den Bergh
Consider a monoidal category which is at the same time abelian with enough projectives and such that projectives are flat on the right. We show that there is a -algebra…
The Frobenius morphism in invariant theory II
Theo Raedschelders, Špela Špenko, Michel Van den Bergh
Let be the homogeneous coordinate ring of the Grassmannian defined over an algebraically closed field of characteristic . In this…
Comparison of two constructions of noncommutative surfaces with exceptional collections of length 4
Pieter Belmans, Dennis Presotto, Michel Van den Bergh
Recently the Euler forms on numerical Grothendieck groups of rank 4 whose properties mimick that of the Euler form of a smooth projective surface have been classified. This classif…
Tilting bundles on hypertoric varieties
Špela Špenko, Michel Van den Bergh
Recently McBreen and Webster constructed a tilting bundle on a smooth hypertoric variety (using reduction to finite characteristic) and showed that its endomorphism ring is Koszul.…
On the noncommutative Bondal-Orlov conjecture for some toric varieties
Špela Špenko, Michel Van den Bergh, with an appendix by Jason P. Bell
We show that all toric noncommutative crepant resolutions (NCCRs) of affine GIT quotients of "weakly symmetric" unimodular torus representations are derived equivalent. This yields…
The Frobenius morphism in invariant theory
Theo Raedschelders, Špela Špenko, Michel Van den Bergh
Let be the homogeneous coordinate ring of the Grassmannian defined over an algebraically closed field of characteristic . In this paper…
