On local non-tangential growth of the resolvent of a banded Toeplitz operator
L. Golinskii, S. Kupin
We study the growth of the resolvent of a Hardy--Toeplitz operator with a Laurent polynomial symbol (\emph{i.e., } the matrix is banded), at the neighborhood of a point…

On the growth of resolvent of Toeplitz operators
Leonid Golinskii, Stanislas Kupin, Anna Vishnyakova
We study the growth of the resolvent of a Toeplitz operator , defined on the Hardy space, in terms of the distance to its spectrum . We are primarily interested in the…
