Quantum Lorentz groups obtained by Rieffel deformation

Kasprzak, P (Warsaw)
Wednesday 20 December 2006, 16:00-16:30

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.
