    Gromov-Witten theory of banded gerbes over schemes
    (SISSA, 2011-01-31) Andreini, Elena; Jiang, Yunfeng; Tseng, Hsian-Hua; Mathematics; Mathematical Physics
    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 $\mathcal{G}$ in terms of those of $X$.
