Deformation theory for a morphism in the derived category with fixed lift of the codomain

Pieter Belmans, Wendy Lowen, Shinnosuke Okawa +1

We develop the deformation-obstruction calculus for morphisms of complexes with a fixed lift of the codomain, to derived categories of flat nilpotent deformations of abelian catego…

Marked Artin--Schelter surfaces of del Pezzo types

Shinnosuke Okawa, Kazushi Ueda

We introduce a class of noncommutative surfaces called Artin--Schelter surfaces of del Pezzo types, which contains del Pezzo surfaces as special cases. We show that the moduli stac…
