Noncommutative projective partial resolutions and quiver varieties

SÃ¸ren Gammelgaard, ÃdÃ¡m Gyenge

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

Quiver Schemes for Nongeneric Stability and Cornering

Lukas Bertsch, SÃ¸ren Gammelgaard, 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…
