Surjective Toeplitz operators [PDF]
, 2004 The authors establish a criterion for the surjectivity of noninjective bounded Toeplitz operators on $H^2\coloneq H^2(T)$ and show that the canonical right inverse of a surjective Toeplitz operator is the product of three Toeplitz operators.

Toeplitz operators via sesquilinear forms [PDF]
, 2018 The classical theory of Toeplitz operators in spaces of analytic functions deals usually with symbols that are bounded measurable functions on the domain in question.

Comptes Rendus. MathématiqueUsing 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.

Products of Several Toeplitz Operators
Journal of Functional Analysis, 2000 Let \(a\in L^\infty\) and \(T_a:H^2\to H^2\) be a Toeplitz operator with symbol \(a\) acting in Hardy space \(H^2\) on the unit disk. The author describes the necessary and sufficient conditions on symbols \(a_j\) of Toeplitz operators \(T_{a_j}\) when the identity \(T_{a_1}T_{a_2}\dots T_{a_n}=T_{a}\), \(a=a_1a_2\dots a_n\), holds for an arbitrary \(n\

On the Growth of the Resolvent of a Toeplitz Operator
Zurnal matematiceskoj fiziki, analiza, geometriiSummary: We study the growth of the resolvent of a Toeplitz operator \(T_b\), defined on the Hardy space, in terms of the distance to its spectrum \(\sigma(T_b)\). We are primarily interested in the case when the symbol \(b\) is a Laurent polynomial (i.e., the matrix \(T_b\) is banded).
