Gromov-Witten theory of banded gerbes over schemes

Andreini, Elena; Jiang, Yunfeng; Tseng, Hsian-Hua (SISSA, 2011-01-31)

Let $X$ be a smooth complex projective algebraic variety. Let $\mathcal{G}$ be a $G$-banded gerbe with $G$ a finite abelian group. We prove an exact formula expressing genus $g$ orbifold Gromov-Witten invariants of ...
Moduli space of pairs over projective stacks

Andreini, Elena (SISSA, 2011-05-27)

Let $\clX$ a projective stack over an algebraically closed field $k$ of characteristic 0. Let $\clE$ be a generating sheaf over $\clX$ and $\clO_X(1)$ a polarization of its coarse moduli space $X$. We define a notion of ...
