Étale and Motivic Homotopy Theory

(joint work with Girja Tripathi) There are two parallel theories of oriented cohomology for algebraic varieties: a purely algebraic theory, typified by the classical Chow ring or the Grothendieck group of vector bundles, and a motivic version, such as motivic cohomology or the full theory of algebraic K-theory. Each side has their own advantages and disadvantages. We will describe a series of comparison results that allow one to compute the geometric part of a motivic theory in purely algebraic terms, starting with (geometric) algebraic cobordism.
