The Cauchy dual subnormality problem for cyclic $2$ -isometries

Akash Anand, Sameer Chavan, Zenon Jan Jabłoński +1

The Cauchy dual subnormality problem asks whether the Cauchy dual operator of a $2$ -isometry is subnormal. Recently this problem has been solved in the negative. Here we show that…

Analytic $m$ -isometries without the wandering subspace property

Akash Anand, Sameer Chavan, Shailesh Trivedi

The wandering subspace problem for an analytic norm-increasing $m$ -isometry $T$ on a Hilbert space $H$ asks whether every $T$ -invariant subspace of $H$ can be gen…

Complete systems of unitary invariants for some classes of $2$ -isometries

Akash Anand, Sameer Chavan, Zenon Jan Jabłoński +1

The unitary equivalence of $2$ -isometric operators satisfying the so-called kernel condition is characterized. It relies on a model for such operators built on operator valued unil…
