A^1-homotopy theory of schemes, by Fabien Morel and Vladimir Voevodsky
In this paper we begin to develope a machinery which we call A^1-homotopy
theory of schemes. All our constructions are based on the intuitive feeling
that if the category of algebraic varieties is in any way similar to the
category of topological spaces then there should exist a homotopy theory of
algebraic varieties where the affine line plays the role of the unit
interval.
