摘要翻译:
我们构造了toric Fano n-折叠中某些1-参数Calabi-Yau超曲面族的motivic上同调类,并应用于局部镜像对称(亏0瞬子数的增长)和非齐次Picard-Fuchs方程。在家庭是经典模块的情况下,类与贝林森的爱森斯坦符号有关;本文计算了这两种循环的Abel-Jacobi映射(或有理调节器)。对于循环基本重合的“模toric”族,我们得到了Villegas、Stienstra和Bertin观察到的现象的motivic(和计算上有效的)解释。

英文摘要:
We construct classes in the motivic cohomology of certain 1-parameter families of Calabi-Yau hypersurfaces in toric Fano n-folds, with applications to local mirror symmetry (growth of genus 0 instanton numbers) and inhomogeneous Picard-Fuchs equations. In the case where the family is classically modular the classes are related to Belinson's Eisenstein symbol; the Abel-Jacobi map (or rational regulator) is computed in this paper for both kinds of cycles. For the "modular toric" families where the cycles essentially coincide, we obtain a motivic (and computationally effective) explanation of a phenomenon observed by Villegas, Stienstra, and Bertin.
