III的直接图像:F-等嵴超转换
Images directes III: F-isocristaux surconvergents
摘要:
这篇文章是一系列的三篇文章中的第三篇,致力于等晶的直接图像:在这里,我们考虑过收敛等晶与弗罗贝纽斯结构。对于可提升的真光滑态射,由于第一篇文章和Frobenius提升的存在性,我们建立了直接象的超收敛。这一结果部分回答了Berthelot关于过收敛F-同晶在适当的光滑态射下的直接象的过收敛的猜想。
英文摘要:
This article is the third one of a series of three articles devoted to direct images of isocrystals: here we consider overconvergent isocrystals with Frobenius structure. For a liftable proper smooth morphism we establish the overconvergence of direct images, owing to the first article and the existence of lifts of Frobenius. This result partially answers a conjecture of Berthelot on the overconvergence of direct images of overconvergent F-isocrystals under a proper smooth morphism.
