The Construction of Numerically Calabi-Yau Orders on Projective Surfaces
Rings and Algebras Algebraic Geometry Numerically Calabi-Yau Orders Projective Surfaces
2011/8/25
Abstract: In this paper, we construct a vast collection of maximal numerically Calabi-Yau orders utilising a noncommutative analogue of the well-known commutative cyclic covering trick. Such orders pl...
Uhlenbeck-Donaldson compactification for framed sheaves on projective surfaces
Framed sheaves moduli spaces Uhlenbeck-Donaldson compactification
2010/11/30
We construct a compactification Mμss of the Uhlenbeck-Donaldson type for the moduli space of slope stable framed bundles. This is a kind of a moduli space of slope semistable framed sheaves.
