The étale topology on is the name for the category of étale -schemes the objects of which are étale morphisms (cf. Etale morphism) and the.
In algebraic geometry, the étale topology is a Grothendieck topology on the category of schemes which has properties similar to the Euclidean topology, but.
tasks, we define and study the pro- étale topology, which is a Grothendieck topology related to the étale topology, and yet better suited for infinite constructions. Etale Mainline 4
