L-adic cohomology
WebDec 1, 2000 · This is the text of two lectures given at the Exponential Sums Conference held at The Hebrew University of Jerusalem in January 1998. In these lectures I reviewed some … In applications to algebraic geometry over a finite field Fq with characteristic p, the main objective was to find a replacement for the singular cohomology groups with integer (or rational) coefficients, which are not available in the same way as for geometry of an algebraic variety over the complex number field. Étale cohomology works fine for coefficients Z/nZ for n co-prime to p, but gives unsatisfactory results for non-torsion coefficients. To get cohomology groups without …

Weblar cohomology of a complex algebraic variety. As a bonus, l-adic cohomology has extra structure: it is a representation of the absolute Galois group Gal(k s=k) (the automorphism group of the separable closure k s over k). The speci c version of l-adic cohomology used in this paper, Hi(X;Z l), means \geometric" etale cohomology Hi et(X ks;Z l ... WebA= vector spaces over Ql, H= l-adic cohomology: X7→H∗(X,Q l).

The … barbara rudnik kinderWebWe discuss classical questions concerning traces of elements of Galois groups or correspondences in l-adic cohomology, mostly over finite or local fields, such as rationality and independence of l, integrality, congruences modulo powers of l or p. We report on the progress that has been made on this topic during the past ten years. barbara rudolphWebI've spent several hours skimming through Milne's Etale Cohomology, the 1994 Motives volume, SGA articles, online searches, etc and I can't seem to determine whether or not $\ell$-adic cohomology forms a Weil cohomology theory when you don't assume you are in some "geometric" situation by making assumptions on the field. barbara rudolph pageWebAbstract.
