具有Brauer群(Z/8Z)的Calabi-Yau三重群^[2]

A Calabi-Yau threefold with Brauer group (Z/8Z)^2

Mark Gross, Simone Pavanelli

摘要:

本文计算了Mark Gross和Sorin Popescu发现的某个Calabi-Yau三重的Brauer群,它是由64个普通二重点构成的(2,2,2,2)型完全交的小分解.我们发现布劳尔群是(Z/8 Z)^2,这是已知的卡-丘三重布劳尔群的最大例子。

英文摘要:

We calculate the Brauer group of a certain Calabi-Yau threefold discovered by Mark Gross and Sorin Popescu, which is a small resolution of a complete intersection of type (2,2,2,2) with 64 ordinary double points. We find the Brauer group is (Z/8Z)^2, which is the largest known example of a Brauer group of a Calabi-Yau threefold.
