*In algebraic geometry , motives or sometimes motifs , following French usage is a theory proposed by Alexander Grothendieck in the s to unify the vast array of similarly behaved cohomology theories such as singular cohomology , de Rham cohomology , etale cohomology , and crystalline cohomology.*

MathOverflow is a question and answer site for professional mathematicians. It only takes a minute to sign up. This does not define the category uniquely, nor does it imply that it exists. There are two concrete candidates that we can construct. The category of Chow motives, which is well-defined, is trivially a category of motives. However, it has some bad properties. For example, it is not Tannakian.

## Motive (algebraic geometry)

It seems that you're in Germany. We have a dedicated site for Germany. The conjectural theory of mixed motives would be a universal cohomology theory in arithmetic algebraic geometry. The monograph describes the approach to motives via their well-defined realizations. This includes a review of several known cohomology theories.

In the s Grothendieck made conjectures as to the existence of a universal framework for cohomology of algebraic varieties called the category of mixed motives. During the 's the conjectural formalism was enriched by conjectures of Deligne, Beilinson, Bloch and others.

Теперь Дэвид Беккер стоял в каменной клетке, с трудом переводя дыхание и ощущая жгучую боль в боку. Косые лучи утреннего солнца падали в башню сквозь прорези в стенах. Беккер посмотрел. Человек в очках в тонкой металлической оправе стоял внизу, спиной к Беккеру, и смотрел в направлении площади. Беккер прижал лицо к прорези, чтобы лучше видеть.
