“…Bang, on his own and with coauthors, has since generalized (4.2) to the Fourier transform in Euclidean space in higher dimensions, as well as to Orlicz spaces and Lorentz spaces (with the appropriate associated operators); see [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], [30], [31], [32] and [33]. In [19], Bang also covers the case of L p -functions on the one-dimensional torus for P (x) = x, again using a complex Paley-Wiener theorem.…”
