Sampling and periodization of generators of Heisenberg modules
Mads Sielemann Jakobsen, Franz Luef
This paper considers generators of Heisenberg modules in the case of twisted group -algebras of closed subgroups of locally compact abelian groups and how the restrction and/o…
Yang-Mills connections on quantum Heisenberg manifolds
Sooran Kang, Franz Luef, Judith A. Packer
We investigate critical points and minimizers of the Yang-Mills functional YM on quantum Heisenberg manifolds , where the Yang-Mills functional is defined on the set of a…
Modulation Spaces as a Smooth Structure in Noncommutative Geometry
Are Austad, Franz Luef
We demonstrate that a class of modulation spaces are examples of a smooth structure on the noncommutative 2-torus in the sense of recent developments in KK-theory. In addition, we…
On accumulated Cohen's class distributions and mixed-state localization operators
Franz Luef, Eirik Skrettingland
Recently we introduced mixed-state localization operators associated to a density operator and a (compact) domain in phase space. We continue the investigations of their eigenvalue…
Time-frequency analysis on the adeles over the rationals
Ulrik B. R. Enstad, Mads S. Jakobsen, Franz Luef
We show that the construction of Gabor frames in with generators in and with respect to time-frequency shifts from a rectangular la…
Duality of Gabor frames and Heisenberg modules
Mads S. Jakobsen, Franz Luef
Given a locally compact abelian group and a closed subgroup in , Rieffel associated to a Hilbert -module , known as a Heisenberg m…
