On the pointwise implementation of near-actions
Asger Tornquist
We show that the continuum hypothesis implies that every measure preserving near-action of a group on a standard Borel probability space has a pointwise implementation by B…
Frame Constants of Gabor Frames near the Critical Density
A. Borichev, K. Gröchenig, Yu. Lyubarskii
We consider Gabor frames generated by a Gaussian function and describe the behavior of the frame constants as the density of the lattice approaches the critical value.
Super-wavelets versus poly-Bergman spaces
Luis Daniel Abreu
Motivated by potential applications in multiplexing and by recent results on Gabor analysis with Hermite windows due to Gröchenig and Lyubarskii, we investigate vector-valued wavel…
The nature of ionized gas in early-type galaxies
F. Annibali, A. Bressan, R. Rampazzo +1
We present a study of the ionized gas in a sample of 65 nearby early-type galaxies, for which we have acquired optical intermediate-resolution spectra. Emission lines are detected…
The structure of alternative tableaux
Philippe Nadeau
In this paper we study alternative tableaux introduced by Viennot. These tableaux are in simple bijection with permutation tableaux, defined previously by Postnikov . We exhibit a…
The Pseudo-Character of the Weil Representation and its Relation with the Conley-Zehnder Index
Maurice de Gosson, Franz Luef
We calculate the character of the Weil representation using previous results which express the Weyl symbol of metaplectic operators in terms of the symplectic Cayley transform and…
