چکیده

à 4.0 Short Comment on Sheaves, Bundles, and Representable Functors. The notion of a sheaf over a topological space X generalize that of a bundle over X . We're more-or-less aware of this. I want to spend some time looking the specifics of this generalization. I'll focus on schemes. Fix a ring A and let 1 :=A 1 be the affine line. The first thing I want to point out is that the global section functor

Notes on Étale Cohomology

These notes outline the “fundamental theorems” of étale cohomology, following [4, Ch. vi], as well as briefly discuss the Weil conjectures.

The Étale Cohomology of p-Torsion Sheaves, II

A formula due to Grothendieck, Ogg, and Shafarevich gives the EulerPoincaré characteristic of a constructible sheaf of Fl-modules on a smooth, proper curve over an algebraically closed field k of characteristic p > 0, as a sum of a global term and local terms, where l 6= p. A previously known result removes the restriction on l in the case of p-torsion sheaves trivialized by p-extensions. The a...

Cohomology Operations and Inverting the Motivic Bott Element

In this note we explore the relationships between the motivic cohomology operations and the (classical) cohomology operations defined on mod-l étale cohomology. More precisely we show that the cohomology operations on motivic cohomology transform to the (classical) cohomology operations on mod-l étale cohomology upon inverting the motivic Bott element.

Notes on Isocrystals

For varieties over a perfect field of characteristic p, étale cohomology with Q`coefficients is a Weil cohomology theory only when ` 6= p; the corresponding role for ` = p is played by Berthelot’s rigid cohomology. In that theory, the coefficient objects analogous to lisse `-adic sheaves are the overconvergent F -isocrystals. This expository article is a brief user’s guide for these objects, in...
