Covariant Poisson structures on complex Grassmannians

N. Ciccoli, A. J. -L. Sheu

The purpose of this paper is to study covariant Poisson structures on the complex Grassmannian obtained as quotients by coisotropic subgroups of the standard Poisson--Lie SU(n). Pr…

Quantum Spheres As Groupoid C*-algebras

Albert Jeu-Liang Sheu

We show that the C*-algebra of a quantum sphere $C (S_{q}^{2 n + 1})$ can be realized as a groupoid C*-algebra of a groupoid which is explicitly identified and is independent of the pa…

Groupoid Approach to Quantum Projective Spaces

Albert Jeu-Liang Sheu

We show how the C*-algebras of quantum complex projective spaces (standard or nonstandard) are related to groupoids.

Covariant Poisson Structures on Complex Projective Spaces

Albert Jeu-Liang Sheu

We show that the standard SU(n)-covariant Poisson sphere $S^{2 n - 1}$ is embedded in the nonstandard $S U (n + 1)$ -covariant Poisson complex projective spaces $C P^{n}$ .
