Norm estimates for quasi-Banach modulation spaces and Wiener-Lebesgue spaces


Christine Pfeuffer, Nenad Teofanov, Joachim Toft




We investigate the relationship between quasi-Banach modulation spaces and Wiener-Lebesgue amalgam spaces. More precisely, we establish norm equivalence for these spaces across the full range of the Lebesgue parameters. Our main result unifies and complements the findings known so far.
