Quiver Schemes for Nongeneric Stability and Cornering

Lukas Bertsch, Søren Gammelgaard

We use the Le Bruyn--Procesi theorem to prove several results on quiver schemes for nongeneric stability conditions: We show that the stability-zero finite-type Nakajima quiver sch…

Noncommutative projective partial resolutions and quiver varieties

Søren Gammelgaard, Ádám Gyenge

Let $Γ \in SL_{2} (C)$ be a finite subgroup. We introduce a class of projective noncommutative surfaces $P_{I}^{2}$ , indexed by a set of irreducible $Γ$ -represen…

Moduli spaces of framed sheaves on compactified Kleinian singularities

Søren Gammelgaard

Consider a Kleinian singularity $C^{2} /Γ$ , where $Γ$ is a finite subgroup of $S L_{2} (C)$ . In this paper, we construct moduli spaces of framed sheaves on a project…

Quiver Varieties and Framed Sheaves on Compactified Kleinian Singularities

Søren Gammelgaard

Consider a Kleinian singularity $C^{2} /Γ$ , where $Γ$ is a finite subgroup of $S L_{2} (C)$ . In this paper, we introduce a natural stack compactifying the singularit…

Quot schemes for Kleinian orbifolds

Alastair Craw, Søren Gammelgaard, Ádám Gyenge +1

For a finite subgroup $Γ \subset SL (2, C)$ , we identify fine moduli spaces of certain cornered quiver algebras, defined in earlier work, with orbifold Quot scheme…

Punctual Hilbert schemes for Kleinian singularities as quiver varieties

Alastair Craw, Søren Gammelgaard, Ádám Gyenge +1

For a finite subgroup $Γ \subset SL (2, C)$ and $n \geq 1$ , we construct the (reduced scheme underlying the) Hilbert scheme of $n$ points on the Kleinian singularity…
