Exact essential norm of generalized Hilbert matrix operators on classical analytic function spaces
Mikael Lindström, Santeri Miihkinen, David Norrbo
We compute the exact value of the essential norm of a generalized Hilbert matrix operator acting on weighted Bergman spaces and weighted Banach spaces of analy…
Unified approach to spectral properties of multipliers
Mikael Lindström, Santeri Miihkinen, David Norrbo
Let be the open unit ball in . We characterize the spectra of pointwise multipliers acting on Banach spaces of analytic functions on …
On the exact value of the norm of the Hilbert matrix operator on weighted Bergman spaces
Mikael Lindström, Santeri Miihkinen, Niklas Wikman
In this article, the open problem of finding the exact value of the norm of the Hilbert matrix operator on weighted Bergman spaces is adressed. The norm was conjectured to…
Rigidity of weighted composition operators on
Mikael Lindström, Santeri Miihkinen, Pekka J. Nieminen
We show that every non-compact weighted composition operator acting on a Hardy space for fixes an isomorphic copy of the sequ…
Toeplitz operators with piecewise continuous symbols on the Hardy space
Santeri Miihkinen, Jani A. Virtanen
The geometric descriptions of the (essential) spectra of Toeplitz operators with piecewise continuous symbols are among the most beautiful results about Toeplitz operators on Hardy…
Norm estimates of weighted composition operators pertaining to the Hilbert Matrix
Mikael Lindström, Santeri Miihkinen, Niklas Wikman
Very recently, Božin and Karapetrović solved a conjecture by proving that the norm of the Hilbert matrix operator on the Bergman space is equal to $\fracπ{\sin(…
