关于射影空间上Fano丛的量子上同调

On the quantum cohomology of Fano bundles over projective spaces

Vincenzo Ancona, Marco Maggesi

摘要:

在他们的论文“Quantum cohomology of projective bundles over $P^n$“(Trans. Am. Math. Soc.(1998)350:9 3615-3638)Z.Qin和Y.Ruan介绍了计算流形的量子环的有趣技巧,这些流形是射影空间上的射影化丛;特别地,在分裂丛的情况下,他们在一些限制下证明了关于环面流形的量子环的Batyrev公式。在这里,我们证明了Batyrev公式的量子Chern-Leray方程的一大类分裂丛。

英文摘要:

In their paper "Quantum cohomology of projective bundles over $P^n$" (Trans. Am. Math. Soc. (1998)350:9 3615-3638) Z.Qin and Y.Ruan introduce interesting techniques for the computation of the quantum ring of manifolds which are projectivized bundles over projective spaces; in particular, in the case of splitting bundles they prove under some restrictions the formula of Batyrev about the quantum ring of toric manifolds. Here we prove the formula of Batyrev on the quantum Chern-Leray equation for a large class of splitting bundles.
