Decay of coefficients and approximation rates in Gabor Gaussian frames

T. Chaumont-Frelet, M. Ingremeau

The aim of this note is to present a self-contained proof of the fact that a function can be approximated using a linear combination of Gaussian coherent states, with a number of t…

Efficient approximation of high-frequency Helmholtz solutions by Gaussian coherent states

T. Chaumont-Frelet, V. Dolean, M. Ingremeau

We introduce new finite-dimensional spaces specifically designed to approximate the solutions to high-frequency Helmholtz problems with smooth variable coefficients in dimension $d…
