过收敛等晶体对数可拓性的截线判据

Cut-by-curves criterion for the log extendability of overconvergent isocrystals

Atsushi Shiho

摘要:

本文证明了特征$p>0$域上光滑簇上过收敛等晶的“曲线切割准则”,在一定的假设下,将其推广到其补为严格正规交叉因子的光滑紧化.这是一个$p$ -adic模拟的一个版本的切的曲线标准的定期奇异性的可积连接上的光滑簇在一个领域的特征0。在证明过程中,我们还证明了一类关于$\nabla$ -模的可解性、最高分歧断裂和指数的曲线截割准则。

英文摘要:

In this paper, we prove a `cut-by-curves criterion' for an overconvergent isocrystal on a smooth variety over a field of characteristic $p>0$ to extend logarithmically to its smooth compactification whose complement is a strict normal crossing divisor, under certain assumption. This is a $p$-adic analogue of a version of cut-by-curves criterion for regular singuarity of an integrable connection on a smooth variety over a field of characteristic 0. In the course of the proof, we also prove a kind of cut-by-curves criteria on solvability, highest ramification break and exponent of $\nabla$-modules.
