A virtual $PGL_{r}$ - $SL_{r}$ correspondence for projective surfaces

D. van Bree, A. Gholampour, Y. Jiang +1

For a smooth projective surface $X$ satisfying $H_{1} (X, Z) = 0$ and $w \in H^{2} (X, I^¼_{r})$ , we study deformation invariants of the pair $(X, w)$ . Choosing a Brauer-Severi variet…

Euler characteristics of moduli of twisted sheaves on Enriques surfaces

Dirk van Bree, Weisheng Wang

Let $Y$ be an Enriques surface and let $A$ be an Azumaya algebra corresponding to the non-trivial Brauer class. Let $M$ be the moduli space of stable twisted sheaves on E…
