  skos:definition """En mathématiques, la K-théorie est un outil utilisé dans plusieurs disciplines. En topologie algébrique, la K-théorie topologique sert de théorie de cohomologie. Une variante est utilisée en algèbre sous le nom de K-théorie algébrique. Les premiers résultats de la K-théorie ont été dans le cadre de la topologie algébrique, comme une théorie de cohomologie extraordinaire (elle ne vérifie pas l'axiome de dimension). Par la suite, ces méthodes ont été utilisées dans beaucoup d'autres domaines comme la géométrie algébrique, l'algèbre, la théorie des nombres, la théorie des opérateurs, etc.

In algebraic topology, it is a cohomology theory known as topological K-theory. In algebra and algebraic geometry, it is referred to as algebraic K-theory. It is also a fundamental tool in the field of operator algebras. It can be seen as the study of certain kinds of invariants of large matrices. K-theory involves the construction of families of <i>K</i>-functors that map from topological spaces or schemes to associated rings; these rings reflect some aspects of the structure of the original spaces or schemes. As with functors to groups in algebraic topology, the reason for this functorial mapping is that it is easier to compute some topological properties from the mapped rings than from the original spaces or schemes. Examples of results gleaned from the K-theory approach include the Grothendieck–Riemann–Roch theorem, Bott periodicity, the Atiyah–Singer index theorem, and the Adams operations.
