Quantum Lorentz groups obtained by Rieffel deformation
Seminar Room 1, Newton Institute
The aim of this talk is to describe two examples of Quantum Lorentz Groups obtained by Rieffel Deformation. In particular, a description in terms of noncommutative coordinates on them will be given. If time permits, we will present a refinement of Rieffel Deformation, based on Landstad theory of crossed product. The benefits of this approach are: simple proofs of invariance of K-theory and preservation of nuclearity under the deformation.
