摘要翻译:
我们计算了Calabi-Yau超曲面的约化亏格1Gromov-Witten不变量。因此,我们证实了1993年Bershadsky-Cecotti Ooguri-Vafa(BCOV)对标准亏格1 GW-不变量的预测。我们将一系列文献的构造与经典局部化定理相结合,将CY超曲面的约化亏格1不变量与射影空间中稳定亏格0映射的模空间上的积分联系起来。由此得到的关于1属等变母函数的相当笨拙的表达式,在一半的情况下使用了0属等变母函数的正则性,从而大大简化了。最后,通过忽略不能影响前者的非等变部分的项,我们以一种简单的方式将答案与一个显式超几何级数联系起来。本文所述的方法是系统的。它直接适用于计算其它完全交集的约化亏格1 GW-不变量,也适用于更高亏格的局部化计算。

英文摘要:
We compute the reduced genus 1 Gromov-Witten invariants of Calabi-Yau hypersurfaces. As a consequence, we confirm the 1993 Bershadsky-Cecotti Ooguri-Vafa (BCOV) prediction for the standard genus 1 GW-invariants of a quintic threefold. We combine constructions from a series of previous papers with the classical localization theorem to relate the reduced genus 1 invariants of a CY-hypersurface to previously computed integrals on moduli spaces of stable genus 0 maps into projective space. The resulting, rather unwieldy, expressions for a genus 1 equivariant generating function simplify drastically, using a regularity property of a genus 0 equivariant generating function in half of the cases. Finally, by disregarding terms that cannot effect the non-equivariant part of the former, we relate the answer to an explicit hypergeometric series in a simple way. The approach described in this paper is systematic. It is directly applicable to computing reduced genus 1 GW-invariants of other complete intersections and should apply to higher-genus localization computations.
