A higher Kac-Moody extension for two-dimensional gauge groups
Jens Kaad, Ryszard Nest, Jesse Wolfson
Let be a finite dimensional Lie group and consider the smooth double loop group, i.e. the Fréchet Lie group of smooth maps from the 2-torus to . For a finite dimensional Hil…
Polynomial approximation of quantum Lipschitz functions
Konrad Aguilar, Jens Kaad, David Kyed
We prove an approximation result for Lipschitz functions on the quantum sphere , from which we deduce that the two natural quantum metric structures on have quantum…
The Podles spheres converge to the sphere
Konrad Aguilar, Jens Kaad, David Kyed
We prove that the Podles spheres converge in quantum Gromov-Hausdorff distance to the classical 2-sphere as the deformation parameter tends to 1. Moreover, we construct…
Kernels of Hilbert Module Maps: A Counterexample
Jens Kaad, Michael Skeide
Answering a long standing question, we give an example of a Hilbert module and a nonzero bounded right linear map having a kernel with trivial orthogonal complement. In particular,…
