    • The affine Wigner distribution 

      Berge, Eirik; Berge, Stine Marie; Luef, Franz (Peer reviewed; Journal article, 2022)
      We examine the affine Wigner distribution from a quantization perspective with an emphasis on the underlying group structure. One of our main results expresses the scalogram as (affine) convolution of affine Wigner ...

    • A fractal uncertainty principle for the short-time Fourier transform and Gabor multipliers 

      Knutsen, Helge (Peer reviewed; Journal article, 2023)
      We study the fractal uncertainty principle in the joint time-frequency representation, and we prove a version for the Short-Time Fourier transform with Gaussian window on the modulation spaces. This can equivalently be ...
