Compactification of the moduli space of minimal instantons on the Fano threefold $V_{4}$

Xuqiang Qin

We study semi-stable sheaves of rank $2$ with Chern class $c_{1} = 0$ , $c_{2} = 2$ and $c_{3} = 0$ on the Fano 3-folds $V_{4}$ of Picard number $1$ , degree $4$ and index $2$ . We show the moduli…

Compactification of the moduli space of instanton sheaves on the Fano threefold $V_{5}$

Xuqiang Qin

We study semistable sheaves of rank $2$ with Chern classes $c_{1} = 0$ , $c_{2} = 2$ and $c_{3} = 0$ on the Fano 3-fold $V_{5}$ of Picard number $1$ , degree $5$ and index $2$ . We show that the mo…

Blow ups of $P^{n}$ as quiver moduli for exceptional collections

Xuqiang Qin

Suppose $P_{m}^{n}$ is the blow up of $P^{n}$ at a linear subspace of dimension $m$ , $L = {L_{1}, \dots, L_{r}}$ is a (not necessarily full) strong exceptional collection o…

Moduli of quiver representations for exceptional collections on surfaces

Xuqiang Qin, Shizhuo Zhang

Suppose $S$ is a smooth projective surface over an algebraically closed field $k$ , $L = {L_{1}, \dots, L_{n}}$ is a full strong exceptional collection of line bundles on $S$ .…
