The quantum Euclidean spheres, S N-1 q , are (noncommutative) homogeneous spaces of quantum orthogonal groups, SO q (N). The \* -algebra A(S N-1 q ) of polynomial functions on each of these is given by generators and relations which can be expressed in terms of a self-adjoint, unipotent matrix. We e

โฆ Synopsis
We show that the relations which define the algebras of the quantum Euclidean planes R N q can be expressed in terms of projections provided that the unique central element, the radial distance from the origin, is fixed. The resulting reduced algebras without center are the quantum Euclidean spheres S N-1 q . The projections e = e 2 = e * are elements in Mat 2 n (S N-1 q ), with N = 2n + 1 or N = 2n, and can be regarded as defining modules of sections of q-generalizations of monopoles, instantons or more general twisted bundles over the spheres. We also give the algebraic definition of normal and cotangent bundles over the spheres in terms of canonically defined projections in Mat N (S N-1 q

We study some aspects of the theory of non-commutative differential calculi over complex algebras, especially over the Hopf algebras associated to compact quantum groups in the sense of S.L. Woronowicz. Our principal emphasis is on the theory of twisted graded traces and their associated twisted cyc
