Torus equivariant spectral triples for odd dimensional quantum spheres coming from C-extensions

چکیده
The torus group (S) has a canonical action on the odd dimensional sphere S q . We take the natural Hilbert space representation where this action is implemented and characterize all odd spectral triples acting on that space and equivariant with respect to that action. This characterization gives a construction of an optimum family of equivariant spectral triples having nontrivial K-homology class thus generalizing our earlier results for SUq(2). We also relate the triple we construct with the C ∗-extension 0 −→ K⊗ C(S) −→ C(S q ) −→ C(S 2l+1 q ) −→ 0. AMS Subject Classification No.: 58B34, 46L87, 19K33

Characterization of SUq(l + 1)-equivariant spectral triples for the odd dimensional quantum spheres
Abstract The quantum group SUq(l + 1) has a canonical action on the odd dimensional sphere S q . All odd spectral triples acting on the L2 space of S 2l+1 q and equivariant under this action have been characterized. This characterization then leads to the construction of an optimum family of equivariant spectral triples having nontrivial K-homology class. These generalize the results of Chakrab...
متن کاملEquivariant spectral triples for SUq(l + 1) and the odd dimensional quantum spheres
We formulate the notion of equivariance of an operator with respect to a covariant representation of a C∗-dynamical system. We then use a combinatorial technique used by the authors earlier in characterizing spectral triples for SUq(2) to investigate equivariant spectral triples for two classes of spaces: the quantum groups SUq(l+1) for l > 1, and the odd dimensional quantum spheres S q of Vaks...
متن کاملRegularity and dimension spectrum of the equivariant spectral triple for the odd dimensional quantum spheres
The odd dimensional quantum sphere S q is a homogeneous space for the quantum group SUq(l + 1). A generic equivariant spectral triple for S 2l+1 q on its L2 space was constructed by Chakraborty & Pal in [4]. We prove regularity for that spectral triple here. We also compute its dimension spectrum and show that it is simple. We give detailed construction of its smooth function algebra and some r...
متن کاملEquivariant spectral triples on the quantum SU(2) group
We characterize all equivariant odd spectral triples on the quantum SU(2) group having a nontrivial Chern character. It is shown that the dimension of an equivariant spectral triple is at least three, and there does exist a 3-summable equivariant spectral triple. We also show that given any odd spectral triple, there is an odd equivariant spectral triple that induces the same element in K. AMS ...
متن کاملDirac Operators on Quantum Projective Spaces
We construct a family of self-adjoint operators DN , N ∈ Z, which have compact resolvent and bounded commutators with the coordinate algebra of the quantum projective space CPq, for any ` ≥ 2 and 0 < q < 1. They provide 0-dimensional equivariant even spectral triples. If ` is odd and N = 1 2 (` + 1), the spectral triple is real with KO-dimension 2` mod 8.
