Abstract
We show that the Virasoro conjecture in Gromov–Witten theory holds for the the total space of a toric bundle $E \to B$ if and only if it holds for the base B. The main steps are: (i) We establish a localization formula that expresses Gromov–Witten invariants of E, equivariant with respect to the fiberwise torus action in terms of genus-zero invariants of the toric fiber and all-genus invariants of B, and (ii) we pass to the nonequivariant limit in this formula, using Brown’s mirror theorem for toric bundles.
我们证明了格罗莫夫-维滕理论中的维拉索罗猜想（Virasoro conjecture）在环束 $E \to B$ 的总空间中成立，前提是且仅当它在基 B 中成立时：(i) 我们建立了一个局部化公式，用环状纤维的零属不变式和 B 的全属不变式来表达 E 的格罗莫夫-维滕不变式，相对于纤维环状作用等变，以及 (ii) 我们利用布朗关于环状束的镜像定理来传递这个公式中的非变极限。
$E \to B$ if and only if it holds for the base B. The main steps are: (i) We establish a localization formula that expresses Gromov–Witten invariants of E, equivariant with respect to the fiberwise torus action in terms of genus-zero invariants of the toric fiber and all-genus invariants of B, and (ii) we pass to the nonequivariant limit in this formula, using Brown’s mirror theorem for toric bundles.
