Splitting of the virtual class for genus one stable quasimaps

扫码查看
We analyze the local structure of the moduli space of genus one stable quasimaps.Combining it with the p-fields theory developed by Chang and Li(2020),we prove the splitting formula for the virtual cycle of stable quasimaps to complete intersections in Pn.
