Structural rigidity of generalised Volterra operators on $H^{p}$

Santeri Miihkinen, Pekka J. Nieminen, Eero Saksman +1

We show that the non-compact generalised analytic Volterra operators $T_{g}$ , where $g \in BMOA$ , have the following structural rigidity property on the Hardy spaces $H^{p}$ f…

Optimal growth of harmonic functions frequently hypercyclic for the partial differentiation operator

Clifford Gilmore, Eero Saksman, Hans-Olav Tylli

We solve a problem posed by Blasco, Bonilla and Grosse-Erdmann in 2010 by constructing a harmonic function on $R^{N}$ , that is frequently hypercyclic with respect to the par…

On universal operators and universal pairs

Riikka Schroderus, Hans-Olav Tylli

We study some basic properties of the class of universal operators on Hilbert space, and provide new examples of universal operators and universal pairs.
