K-inner functions and K-contractions

Jörg Eschmeier, Sebastian Toth

For a large class of unitarily invariant reproducing kernel functions $K$ on the unit ball $B_{d}$ in $C^{d}$ , we characterize the $K$ -inner functions on $B_{d}$ …

Wandering subspace property for homogeneous invariant subspaces

Jörg Eschmeier

For graded Hilbert spaces $H$ and shift-like commuting tuples $T \in B (H)^{n}$ , we show that each homogeneous joint invariant subspace $M$ of $T$ has finite index and is generated by…

Multivariable Bergman shifts and Wold decompositions

Jörg Eschmeier, Sebastian Langendörfer

Let $H_{m} (B)$ be the analytic functional Hilbert space on the unit ball $B \subset C^{n}$ with reproducing kernel $K_{m} (z, w) = (1 - ⟨ z, w ⟩)^{- m}$ .…

Toeplitz operators with pluriharmonic symbol

Jörg Eschmeier, Sebastian Langendörfer

Let $m \geq 1$ be an integer and let $H_{m} (B)$ be the analytic functional Hilbert space on the unit ball $B \subset C^{n}$ given by the reproducing kernel $K_m…

On Schatten-class perturbations of Toeplitz operators

Michael Didas, Jörg Eschmeier, Dominik Schillo

We characterize the commutant of the analytic Toeplitz operators modulo operators of Schatten-p-class on suitable multivariable domains. We show that a result of J. Xia on compact…

Cowen-Douglas tuples and fiber dimensions

Jörg Eschmeier, Sebastian Langendörfer

Let T be a Cowen-Douglas tuple on a Banach space X. We use functional representations of T to associate with each T-invariant subspace Y of X an integer called the fiber dimension…
