对数非阿贝尔Hodge理论

Logarithmic nonabelian Hodge theory in characteristic p

Daniel Schepler

摘要:

给定特征$p > 0$的对数概型的态射$X \to S$和$X'$在$S$模$p^2$上的提升,利用Lorenzon指标代数$A_X^{gp}$和$B_{X/S}$构造了具有幂零可积联络的$O_X$ -模与具有幂零$B_{X/S}$ -线性Higgs场的指标$B_{X/S}$ -模之间的等价关系.如果任何一个满足一个更严格的零条件,我们发现一个同构之间的德拉姆上同调的连接和希格斯场的希格斯上同调。

英文摘要:

Given a morphism $X \to S$ of log schemes of characteristic $p > 0$ and a lifting of $X'$ over $S$ modulo $p^2$, we use Lorenzon's indexed algebras $A_X^{gp}$ and $B_{X/S}$ to construct an equivalence between $O_X$-modules with nilpotent integrable connection and indexed $B_{X/S}$-modules with nilpotent $B_{X/S}$-linear Higgs field. If either satisfies a stricter nilpotence condition, we find an isomorphism between the de Rham cohomology of the connection and the Higgs cohomology of the Higgs field.
