Main Page See live article Alphabetical index Étale cohomology In mathematics , the étale cohomology theory of algebraic geometry is a refined construction of homological algebra , introduced in order to attack the Weil conjectures . This proved successful as a strategy, about a dozen years after the idea was mooted in the early 1960s. The formal definition of étale cohomology is as the derived functor sheaf . The sections of a sheaf can be thought of as Hom( Z ,F) where Z is the sheaf returning always the integers as abelian group ; the sheaf F is understood in the sense of a Grothendieck topology . The idea of derived functor here is that the sheaf of sections doesn't respect exact sequences; according to general principles of homological algebra there will be a sequence of functors H i for i = 0,1, ... that represent the 'compensations' that must be made in order to restore some measure of exactness (long exact sequences arising from short ones). The H In these very abstract terms, the existence of such a theory comes down to some properties of étale morphisms in scheme theory , allowing us to use étale coverings as a Grothendieck topology; and some further proofs in homological terms, showing for example that injective resolutions are to be found in the sheaf category. To a very great extent, this attitude masks what is going on.

Finally, our main theorem is that the existence of particularly elementary bijections can be deduced from the provable existence, in intuitionistic type theory, of any bijections at all.
