On the closed range problem for composition operators on the Dirichlet space

Concrete Operators, 2019
We characterize closed range composition operators on the Dirichlet space for a particular class of composition symbols. The characterization relies on a result about Fredholm Toeplitz operators with BMO1 symbols, and with Berezin transforms of vanishing

Factorization of Hankel operators, range inclusion of Toeplitz and Hankel operators on the vector-valued Hardy space

Comptes Rendus. Mathématique
Using Douglas theorem on factorization and range inclusion of bounded linear operators, we give the factorization of Hankel operators, range inclusion of Hankel and Toeplitz operators defined on vector-valued Hardy spaces.

Toeplitz Operators on the Weighted Bergman Space over the Two-Dimensional Unit Ball

Journal of Function Spaces, 2015
We extend the known results on commutative Banach algebras generated by Toeplitz operators with radial quasi-homogeneous symbols on the two-dimensional unit ball.

Hyponormal Toeplitz Operators on the Dirichlet Spaces

Abstract and Applied Analysis, 2013
We completely characterize the hyponormality of bounded Toeplitz operators with Sobolev symbols on the Dirichlet space and the harmonic Dirichlet space.

Improper filtrations for C*-algebras: spectra of unilateral tridiagonal operators

, 1992
We extend the results of our previous paper "C*-algebras and numerical linear algebra" to cover the case of "unilateral" sections. This situation bears a close resemblance to the case of Toeplitz operators on Hardy spaces, in spite of the fact that the ...

Perturbation of Toeplitz operators and reflexivity

Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2014
It was shown that the space of Toeplitz operators perturbated by finite rank operators is 2-hyperreflexive.
