Manifolds, Sheaves, and Cohomology / This book explains techniques that are essential in almost all branches of modern geometry such as algebraic geometry, complex geometry, or non-archimedian geometry. It uses the most accessible case, real and complex manifolds, as a model. The author especially emphasizes the difference between loca. Etale cohomology is an important branch in arithmetic geometry. This book covers the main materials in SGA 1, SGA 4, SGA 4 1/2 and SGA 5 on etale cohomology theory, which includes decent theory, etale fundamental groups, Galois cohomology, etale cohomology, derived categories, base change theorems, duality, and l-adic cohomology.

Denote by ShX the category of sheaves of abelian groups deﬁned on X and by Abgr the category of abelian groups. ShX is an abelian category and has enough injectives since every sheaf F PShX can be mapped F ãÑ ¹ xPX Fx ãÑ ¹ xPX Ix pq where the second map is the direct product of stalkwise injections Fx ãÑIx into injective.

I need a good reference book where I can learn the cohomology of sheaves through the approach of Čech cohomology. The Hartshorne's book, for example, doesn't help me a lot because he choose the "derived functors approach".

The central work for the study of sheaf cohomology is Grothendieck's Tôhoku paper. The general theory of sheaves is very limited and no essential result is obtainable without turn ing to particular classes of topological spaces.

Singular cohomology. Singular cohomology is a powerful invariant in topology, associating a graded-commutative ring to any topological space. Every continuous map f: X → Y determines a homomorphism from the cohomology ring of Y to that of X; this puts strong restrictions on the possible maps from X to more subtle invariants such as homotopy groups, the cohomology ring tends to be.

In fact, comparing sheaf cohomology to de Rham cohomology and singular cohomology provides a proof of de Rham's theorem that the two cohomology theories are isomorphic. A different approach is by Čech cohomology. Čech cohomology was the first cohomology theory developed for sheaves and it is well-suited to concrete calculations.

The aim of the book is to present a precise and comprehensive introduction to the basic theory of derived functors, with an emphasis on sheaf cohomology and spectral sequences. It keeps the treatment as simple as possible, aiming at the same time to provide a number of examples, mainly from sheaf theory, and also from algebra.

Modern algebraic geometry is built upon two fundamental notions: schemes and sheaves. The theory of schemes is presented in the first part of this book (Algebraic Geometry 1: From Algebraic Varieties to Schemes, AMS,Translations of Mathematical Monographs, Volume ).

In the present book, the author turns to the theory of sheaves and their cohomology.3/5(1). I personally won't recommend Bredon's book, rather Iversen's "Cohomology of sheaves" (especially if you are interested in the topological aspects/applications of sheaf theory).

There is also Dimca's "Sheaves in topology". However I should say that the epigraph to this (very good) book is "Do not shoot the pianist", and maybe not without a reason.

Of course, a lot of the general stuff about sites, sheaves, etc., is the same either way. $\endgroup$ – Keenan Kidwell Nov 10 '11 at 4 $\begingroup$ Both his course notes and his text book are good, but they are quite different.

In fact, one can regard this functor as $\mathcal{F} \mapsto \hom_{\mathrm{sheaves}}(\ast, \mathcal{F})$ where $\ast$ is the constant sheaf with one element (the terminal object in the category of all -- not necessarily abelian -- sheaves, so sheaf cohomology can be recovered from the full category of sheaves, or the "topos:" it is a fairly.In the present book, Ueno turns to the theory of sheaves and their cohomology.
