Spectral triples and associated Connes-de Rham complex for the quantum $SU(2)$ and the quantum sphere
Partha Sarathi Chakraborty and Arupkumar Pal
In this article, we take up the construction of spectral triples and associated calculus in the context of $SU_q (2)$ and $S_{qc}$. In order to construct explicit spectral triples, we begin with the computation of $K$-groups, and then from explicit generators we construct spectral triples which induce generating elements in $K$-homology. Using these spectral triples, we compute a modified version of the space of Connes-de Rham forms and the associated calculus. The space of $L^2$ forms have also been described explicitly.
