EXAMPLES OF MODULAR FREDHOLM MODULES

I will present examples of modular Fredholm modules for SUq(2) and the family of Podles. spheres. This will include the "standard" modular Fredholm modules (based on irreducible representations) as well as modular Fredholm modules arising from spectral triples. The latter construction shall be used to discuss how to find generators of the C*-algebra of the Heegaard and mirror quantum spheres that would be suitable to describe their geometry.

CLASSIFICATION OF QUANTUM HOMOGENEOUS SPACES

We study actions of compact quantum groups in operator algebras from the categorical point of view. The ergodic actions admit particularly nice classification in terms of the category of equivariant Hilbert modules. For the case of quantum SU(2), we obtain a simple description of equivariant homomorphisms and K-groups based on the categorical structure of such modules. Based on joint work with Kenny De Commer.
