%0 Journal Article %T Quantum Isometry Groups of Noncommutative Manifolds Obtained by Deformation Using Dual Unitary 2-Cocycles %A Debashish Goswami %A Soumalya Joardar %J Mathematics %D 2013 %I arXiv %R 10.3842/SIGMA.2014.076 %X It is proved that the (volume and orientation-preserving) quantum isometry group of a spectral triple obtained by deformation by some dual unitary 2-cocycle is isomorphic with a similar twist-deformation of the quantum isometry group of the original (undeformed) spectral triple. This result generalizes similar work by Bhowmick and Goswami for Rieffel-deformed spectral triples in [Comm. Math. Phys. 285 (2009), 421-444, arXiv:0707.2648]. %U http://arxiv.org/abs/1307.4850v5
