FOURIER-TYPE TRANSFORMS ON REARRANGEMENT-INVARIANT QUASI-BANACH FUNCTION SPACES

open access: yesGlasgow Mathematical Journal, 2018
AbstractWe establish the mapping properties of Fourier-type transforms on rearrangement-invariant quasi-Banach function spaces. In particular, we have the mapping properties of the Laplace transform, the Hankel transforms, the Kontorovich-Lebedev transform and some oscillatory integral operators.

Linear operators, Fourier integral operators and k-plane transforms on rearrangement-invariant quasi-Banach function spaces

Positivity, 2020
The main result of this paper concerns the mapping properties of linear operators on rearrangement-invariant quasi-Banach function spaces. It extends Boyd's interpolation theorem to the case where the linear operator \(T: L^p\rightarrow L^q\) is bounded with \(p\not= q\).

Inequality of spectral bound and growth bound for positive semigroups in rearrangement invariant Banach function spaces

Archiv Der Mathematik, 1996
Extending a recent example of Arendt, we study the semigroup \(T(t)f(s)= f(se^t)\) in rearrangement invariant Banach function spaces over \((1,\infty)\) and obtain various abstract conditions under which equality of spectral bound and growth bound fails.

Sublinear operators on radial rearrangement-invariant quasi-Banach function spaces

Acta Mathematica Hungarica, 2019
Rearrangement-invariant quasi-Banach function spaces (r.i.q. B.f.s) on \(\mathbb{R}^n\) are defined as quasi-normed spaces \(X\) that are rearrangement invariant with associated quasi-norm \(\rho_X\), defined on measurable functions on \([0,\infty)\), satisfying certain monotonicity conditions, and \(\Vert f\Vert_X=\rho_X(f^\ast)\) where \(f^\ast:[0 ...
