On the Smoothness of the Noncommutative Pillow and Quantum Teardrops

Recent results by Krähmer [Israel J. Math. 189 (2012), 237-266] on smoothness of Hopf-Galois extensions and by Liu [arXiv:1304.7117] on smoothness of generalized Weyl algebras are used to prove that the coordinate algebras of the noncommutative pillow orbifold [Internat. J. Math. 2 (1991), 139-166],...

This paper is a contribution to the Special Issue on Noncommutative Geometry and Quantum Groups in
 honor of Marc A. Rief fel. The full collection is available at http://www.emis.de/journals/SIGMA/Rieffel.html.
 I would like to thank Ulrich Kr¨ahmer for discussions, Li-Yu Liu for bringing reference [14] to
 my attention, and Piotr M. Hajac and the referees for helpful comments. I am grateful to
 Fields Institute for Research in Mathematical Sciences in Toronto, where these results were first
 presented, for creating excellent research environment and for support.
