Abstract
Associated to the standard SU q (n) R-matrices, we introduce quantum spheresS 2n-1q , projective quantum spaces ℂℙ n-1 q , and quantum Grassmann manifoldsG k(ℂ n q ). These algebras are shown to be homogeneous spaces of standard quantum groups and are also quantum principle bundles in the sense of T. Brzeziński and S. Majid.
