Frame expansions of test functions, tempered distributions, and ultradistributions
Stevan Pilipović, Diana T. Stoeva
The paper is devoted to frame expansions in Fréchet spaces. First we review some results which concern series expansions in general Fréchet spaces via Fréchet and General Fréchet f…
Cubatures on Grassmannians: moments, dimension reduction, and related topics
Anna Breger, Martin Ehler, Manuel Graef +1
We briefly explain the use of cubature points on Grassmannians in numerical analysis.
A multi-scale Gaussian beam parametrix for the wave equation: the Dirichlet boundary value problem
Michele Berra, Maarten V. de Hoop, José Luis Romero
We present a construction of a multi-scale Gaussian beam parametrix for the Dirichlet boundary value problem associated with the wave equation, and study its convergence rate to th…
Rate-Distortion Theory of Finite Point Processes
Günther Koliander, Dominic Schuhmacher, Franz Hlawatsch
We study the compression of data in the case where the useful information is contained in a set rather than a vector, i.e., the ordering of the data points is irrelevant and the nu…
Harmonic analysis in phase space and finite Weyl-Heisenberg ensembles
Luís Daniel Abreu, Karlheinz Gröchenig, José Luis Romero
Weyl-Heisenberg ensembles are translation-invariant determinantal point processes on associated with the Schrödinger representation of the Heisenberg group, and i…
MSE estimates for multitaper spectral estimation and off-grid compressive sensing
Luís Daniel Abreu, José Luis Romero
We obtain estimates for the Mean Squared Error (MSE) for the multitaper spectral estimator and certain compressive acquisition methods for multi-band signals. We confirm a fact dis…
