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…

Weak compactness and essential norms of integration operators

Jussi Laitila, Santeri Miihkinen, Pekka J. Nieminen

Let $g$ be an analytic function on the unit disc and consider the integration operator of the form $T_{g} f (z) = \int_{0}^{z} f g^{'} d ζ$ . We show that on the spaces $H^{1}$ and $B M O A$ the op…
