本文证明多种已知类型的超奇异不可约辛簇在特定Artin不变量条件下具有Tate或超奇异阿贝尔Chow motive,进而其乘积满足超奇异Tate猜想。
AI 中文摘要
我们证明,对于允许提升到特征零的超奇异不可约辛簇,若其形变类型为$K3^{[n]}$、OG6(Artin不变量$\neq$ 4)或OG10(Artin不变量$\neq$ 12),则具有Tate Chow motive;若为$\mathrm{Kum}^n$型(Artin不变量$\neq$ 3),则具有超奇异阿贝尔Chow motive。特别地,这些不可约辛簇的任意乘积满足整个$\ell$-进或晶体上同调环的超奇异Tate猜想。
英文摘要
We prove that for a supersingular irreducible symplectic variety admitting suitable lifting to characteristic zero has Tate Chow motive if it is of deformation type $K3^{[n]}$, OG6 (with Artin invariant $\neq$ 4), or OG10 (with Artin invariant $\neq$ 12), and has supersingular abelian Chow motive if it is of $\mathrm{Kum}^n$-type (with Artin invariant $\neq$ 3). In particular, any product of those irreducible symplectic varieties satisfies the supersingular Tate conjecture for the whole $\ell$-adic or crystalline cohomology ring.
