Fredholmness of Toeplitz operators on the Fock space

Robert Fulsche, Raffael Hagger

The Fredholm property of Toeplitz operators on the $p$ -Fock spaces $F_{α}^{p}$ on $C^{n}$ is studied. A general Fredholm criterion for arbitrary operators from the Toeplitz alge…

The Essential Spectrum of Toeplitz Operators on the Unit Ball

Raffael Hagger

In this paper we study the Fredholm properties of Toeplitz operators acting on weighted Bergman spaces $A_{ν}^{p} (B^{n})$ , where $p \in (1, \infty)$ and $\mathbb{B}^n \subset \ma…

Toeplitz Quantization on Fock Space

Wolfram Bauer, Lewis Coburn, Raffael Hagger

For Toeplitz operators $T_{f}^{(t)}$ acting on the weighted Fock space $H_{t}^{2}$ , we consider the semi-commutator $T_{f}^{(t)} T_{g}^{(t)} - T_{f g}^{(t)}$ , where $t > 0$ is a certain weight par…
