Isometric tuples are hyperreflexive

Adam H. Fuller, Matthew Kennedy

An $n$ -tuple of operators $(V_{1}, ..., V_{n})$ acting on a Hilbert space $H$ is said to be isometric if the row operator $(V_{1}, ..., V_{n}) : H^{n} \to H$ is an isometry. We prove that every…

Essential normality and the decomposability of homogeneous submodules

Matthew Kennedy

We establish the essential normality of a large new class of homogeneous submodules of the finite rank d-shift Hilbert module. The main idea is a notion of essential decomposabilit…
