AI总结:

本文针对 p-adic Steenbrink 复形与杯积不相容问题,用 log crystalline 方法构造 SNCL 对数概形的基本过滤 dga 与复形,并证明其在特征 p>0 完美域上典范同构于 Kim–Hain 对象。

摘要:

我们构造了 log smooth(对数光滑)概形的 log crystalline(对数晶状)复形的导出 PD-Hirsch 扩张理论;为克服文献 [M] 与 [Nak4] 中 p-adic Steenbrink 复形与 X 的 log crystalline 复形的杯积不相容所造成的障碍,我们利用 log crystalline 方法,为一族 log points(对数点)上的 simple normal crossing log scheme(简单正规交叉对数概形)X 构造了一个基本过滤 dga $(H_{{\ m zar},{\ m TW}},P)$ 和一个基本过滤复形 $(H_{\ m zar},P)$。当底 log scheme 是特征 p>0 的完美域的 log point 时,我们证明 $(H_{{\ m zar},{\ m TW}},P)$ 与 $(H_{\ m zar},P)$ 分别典范同构于 [KH] 中 Kim 与 Hain 的过滤 dga 及其过滤复形。

英文摘要:

We construct a theory of the derived PD-Hirsch extension of the log crystalline complex of a log smooth scheme and we construct a fundamental filtered dga $(H_{{\rm zar},{\rm TW}},P)$ and a fundamental filtered complex $(H_{\rm zar},P)$ for a simple normal crossing log scheme $X$ over a family of log points by using the log crystalline method in order to overcome obstacles arising from the incompatibility of the p-adic Steenbrink complexes in [M] and [Nak4] with the cup product of the log crystalline complex of $X$. When the base log scheme is the log point of a perfect field of characteristic $p>0$, we prove that $(H_{{\rm zar},{\rm TW}},P)$ and $(H_{\rm zar},P)$ is canonically isomorphic to Kim and Hain's filtered dga and their filtered complex in [KH], respectively.
