Bounded and compact Toeplitz+Hankel matrices

Torsten Ehrhardt, Raffael Hagger, Jani Virtanen

We show that an infinite Toeplitz+Hankel matrix $T (φ) + H (ψ)$ generates a bounded (compact) operator on $ℓ^{p} (N_{0})$ with $1 \leq p \leq \infty$ if and only if both $T (φ)$ …

Essential Commutants and Characterizations of the Toeplitz Algebra

Raffael Hagger

In this paper we study the Toeplitz algebra, which is generated by Toeplitz operators with bounded symbols on the Fock space $F_{α}^{p}$ . We show that the Toeplitz algebra coincides wi…

Compact Hankel Operators with Bounded Symbols

Raffael Hagger, Jani Virtanen

We discuss the compactness of Hankel operators on Hardy, Bergman and Fock spaces with focus on the differences between the three cases, and complete the theory of compact Hankel op…

Algebras of Toeplitz operators on the $n$ -dimensional unit ball

Wolfram Bauer, Raffael Hagger, Nikolai Vasilevski

We study $C^{*}$ -algebras generated by Toeplitz operators acting on the standard weighted Bergman space $A_{λ}^{2} (B^{n})$ over the unit ball $B^{n}$ in $\mathbb{…

Improved one-sided deviation inequalities under regularity assumptions for product measures

Kevin Tanguy

This note is concerned with lower tail estimates for product measures. Some improved deviation inequalities are obtained for functions satisfying some regularity and monotonicity a…
