Cotangent Bundles as Coadjoint Orbits and Asymptotic Character Formulas
Michael Gjertsen, Alexander Schmeding
We present geometric quantization on cotangent bundles as a special instance of Kirillov's orbit method. To this end, the cotangent bundle is realized as a coadjoint orbit of an in…

On the structure of multivariate Gabor systems and a result on Gaussian Gabor frames
Michael Gjertsen, Franz Luef
We introduce an equivalence relation on the set of lattices in such that equivalent lattices support identical structures of Gabor systems, up to unitary equivale…
