A multi-parameter Hardy type inequality

Eskil Rydhe

This note contains two simple observations. First, by the weak factorization of product $H^{1}$ (Ferguson--Lacey, Lacey--Terwilleger), we obtain a multi-parameter analogue of Hardy's…

On Laplace--Carleson embeddings, and $L^{p}$ -mapping properties of the Fourier transform

Eskil Rydhe

We investigate so-called Laplace--Carleson embeddings for large exponents. In particular, we extend some results by Jacob, Partington, and Pott. We also discuss some related result…

On $m$ -isometric semigroups, and $2$ -isometric cogenerators

Eskil Rydhe

It is known that a $C_{0}$ -semigroup of Hilbert space operators is $m$ -isometric if and only if its generator satisfies a certain condition, which we choose to call $m$ -skew-symmetry…

Cyclic $m$ -isometries, and Dirichlet type spaces

Eskil Rydhe

We consider cyclic $m$ -isometries on a complex separable Hilbert space. Such operators are characterized in terms of shifts on abstract spaces of weighted Dirichlet type. Our resul…
