    • Gaussian Gabor frames, Seshadri constants and generalized Buser-Sarnak invariants 

      Luef, Franz; Wang, Xu (Peer reviewed; Journal article, 2023)
      We investigate the frame set of regular multivariate Gaussian Gabor frames using methods from Kähler geometry such as Hörmander’s - estimate with singular weight, Demailly’s Calabi–Yau method for Kähler currents and a ...

    • Idempotent Fourier multipliers acting contractively on Hp spaces 

      Brevig, Ole Fredrik; Ortega-Cerdà, Joaquim; Seip, Kristian (Peer reviewed; Journal article, 2021)
      We describe the idempotent Fourier multipliers that act contractively on Hp spaces of the d-dimensional torus Td for d≥1 and 1≤p≤∞. When p is not an even integer, such multipliers are just restrictions of contractive ...
