Projective spaces over split forms of division algebras
Lundi, 16 Novembre, 2015 - 14:00
Résumé :
In order to find explicit (motivic) cell structures for certain homogeneous spaces, we introduce a new description for them, using split forms of the classical division algebras of complex, quaternionic and octonionic numbers. We construct the attaching maps for the cell structures using algebro-geometric means. Their geometric realization can be identified, up to homotopy, with the classical Hopf maps.
