Résumé: 
Topologie algébrique  Derived Clifford algebra  
Description: 
Xuan Bach Nguyen The Clifford algebra of a quadratic form is a very classical object which plays an important part in the theory of quadratic form. Several generalizations of the Clifford algebra have been studied, for example, by replacing quadratic forms by polynomial forms of higher degree. The study of these algebras suggest that they can be defined geometrically. In this talk, we will give the adjunction that realizes these generalizations and we will introduce the derived Clifford algebra.
