The structure of CR manifolds
Aristide Tsemo
In this paper we study the topology of pseudo convex CR manifolds whose Reeb flow preserves the Levi metric.
Quadratic categories, Koszul resolutions and operads
Aristide Tsemo
A quadratic algebra is a homogeneous algebra generated by its elements of degree 1. Manin has endowed the category of quadratic algebras with two tensor products. These structures…
Affine manifolds, lagrangian manifolds
Aristide Tsemo
Let be a symplectic manifold endowed with a agrangian foliation , it has been shown by Weinstein [16] hat the symplectic structure of defines on each leaf of…
Kahler, Poisson Geometry of CR Lie groups
A. Tsemo
In this paper we study left invariant CR structures on Lie groups which are compatible with geometric properties as Poisson and kahler properties.
Geometric structures on fields
Aristide Tsemo
Let M be a manifold, and G a Lie group which satisfies the unique extension property. An (M,G) manifold N is a manifold endowed with an atlas (U_i,f_i) where f_i is a diffeomorphis…
An Atiyah-Singer theorem for gerbes
Aristide Tsemo
Let M be a riemannian manifold. The existence of a spin structure on M, enables to study the topology of M. The obstruction to the existence of the spin structure is given by the s…
