Structural rigidity of generalised Volterra operators on
Santeri Miihkinen, Pekka J. Nieminen, Eero Saksman +1
We show that the non-compact generalised analytic Volterra operators , where , have the following structural rigidity property on the Hardy spaces f…

Essential norms and weak compactness of integral operators between weighted Bergman spaces
Santeri Miihkinen, Pekka Nieminen, Wen Xu
We consider Volterra-type integration operators between Bergman spaces induced by weights satisfying a doubling property. We derive estimates for the operator norms, esse…

Weak compactness and essential norms of integration operators
Jussi Laitila, Santeri Miihkinen, Pekka J. Nieminen
Let be an analytic function on the unit disc and consider the integration operator of the form . We show that on the spaces and the op…
