Unbounded derivations on noncommutative spaces and spectral triples
In this talk I will describe natural unbounded derivations on simple examples of noncommutative spaces: the quantum disk and the quantum torus. In particular I will answer the question whether such derivations come from operators with compact parametrix and thus can be used to define spectral triples (joint work with M. McBride, K. Sakai, and S. Rathnayake).
