Generalized flag geometries and manifolds associated to short Z-graded Lie algebras in arbitrary dimension.
Résumé
The object of this note is to define the generalized flag geometry of a graded Lie algebra which corresponds to the generalized projective geometry in the case of 3-gradings. Then we construct a structure of manifold on this generalized flag geometry. This result generalizes a result known for 3-graded Lie algebras to the more general case of (2k + 1)-graded Lie algebras.
