    Sep 01,  · The bivariant cycle cohomology groups are defined for schemes of finite type over a field in terms of the higher Chow groups. They have the origin in the generalization of the simplicial theory to the algebraic geometry setting. Homotopy invariance, suspension maps, and the Gysin sequence find their place here coopsifas.com by: We show that there is a stable homotopy theory of profinite spaces and use it for two main applications. On the one hand we construct an étale topological realization of the stable A1-homotopy theory of smooth schemes over a base field of arbitrary characteristic in analogy to the complex realization functor for fields of characteristic zero.

    My (limited) understanding is that simplicial methods tend to be used whenever you want some kind of nontrivial homotopy theory -- for instance, to get a nice model structure, you use simplicial sets and not just plain sets; to make $\mathbb{A}^1$-homotopy work, you work with simplicial (pre?)sheaves and not just plain sheaves or schemes; to construct the cotangent complex (which if I.

Etale Homotopy of Simplicial Schemes. (AM), Volume Eric M. Friedlander. One purpose of this book is to offer the basic techniques and results of etale homotopy theory to topologists and algebraic geometers who may then apply the theory in their own work.

With a view to such future applications, the author has introduced a number of. In mathematics, especially in algebraic geometry, the étale homotopy type is an analogue of the homotopy type of topological spaces for algebraic varieties.

Roughly speaking, for a variety or scheme X, the idea is to consider étale coverings → and to replace each connected component of U and the higher "intersections", i.e., fiber products:= × × ⋯ × (n+1 copies of U, ≥) by a. April hard Orange accurate download etale homotopy of simplicial.

Isaksen extends Friedlander’s etale topological type to motivic spaces. The etale type of simplicial presheaves on Sm S is the formal extension of a colimit preserving functor of the etale type of schemes. Using a Z/l-model structure, the etale type becomes a left Quillen functor from motivic spaces to the pro-category of simplicial sets.
