Dwork上同调、de Rham上同调与超几何函数

Dwork cohomology, de Rham cohomology, and hypergeometric functions

Alan Adolphson, Steven Sperber

摘要:

在1960年代,德沃克发展了一个p-adic上同调理论的德拉姆类型的品种在有限域,基于迹公式的行动,弗罗贝纽斯运营商的某些空间的p-adic解析函数。人们可以考虑一个纯粹的代数模拟德沃克的理论品种在外地的特征零,并要求什么是这种理论之间的联系和普通德拉姆上同调。N. Katz证明了光滑射影超曲面的Dwork上同调与de Rham上同调的本原部分是一致的,但对于高余维簇的精确关系一直是一个悬而未决的问题。在这篇文章中,我们解决了光滑仿射完全相交的情况。

英文摘要:

In the 1960s, Dwork developed a p-adic cohomology theory of de Rham type for varieties over finite fields, based on a trace formula for the action of a Frobenius operator on certain spaces of p-adic analytic functions. One can consider a purely algebraic analogue of Dwork's theory for varieties over a field of characteristic zero and ask what is the connection between this theory and ordinary de Rham cohomology. N. Katz showed that Dwork cohomology coincides with the primitive part of de Rham cohomology for smooth projective hypersurfaces, but the exact relationship for varieties of higher codimension has been an open question. In this article, we settle the case of smooth affine complete intersections.
