AI中文摘要:
受 Markman 的工作及 Kontsevich 用热带方法反驳 Hodge 猜想的启发,本文解释了为何 Weil 型阿贝尔 2n 维族仅在判别式为 $(-1)^n$ 时具有极大幂幺退化。文中还阐明了判别式的定义,并汇集了 Weil 型阿贝尔簇的若干事实。
英文摘要:
Motivated by Markman's work and by Kontsevich's tropical approach to disproving the Hodge conjecture, this note explains why families of Weil type abelian 2n-folds only have maximal unipotent degeneration when the discriminant is $(-1)^n$. Along the way, it explains what the discriminant is and collects various facts about Weil type abelian varieties.
