本研究公告讨论了我们关于根细菌Gromov-Witten理论的结果。通过对虚基类的直接分析,得到了光滑基格式上$\mu_{r}$-根gerbes的亏格0Gromov-Witten理论的一个完全计算。我们的结果验证了所谓分解猜想的0属部分,它将格贝斯的Gromov-Witten理论与基的Gromov-Witten理论进行了比较。我们还在toric Deligne-Mumford堆上的toric gerbes的所有属上验证了这个猜想。

英文摘要:
This research announcement discusses our results on Gromov-Witten theory of root gerbes. A complete calculation of genus 0 Gromov-Witten theory of $\mu_{r}$-root gerbes over a smooth base scheme is obtained by a direct analysis of virtual fundamental classes. Our result verifies the genus 0 part of the so-called decomposition conjecture which compares Gromov-Witten theory of \'etale gerbes with that of the bases. We also verify this conjecture in all genera for toric gerbes over toric Deligne-Mumford stacks.
