Asymptotic Rigidity and Boundary Structure of Yang's Numerical Invariants for the Bidisk Submodules

Yin Liu, Yufeng Lu, Yixin Yang

Let \[ M_{k,\ell}=[z^k-w^\ell]\subset H^2(\mathbb D^2), \qquad k,\ell\in\mathbb N,\quad k\ne\ell . \] We study the large-index asymptotics of Yang's numerical invariants and the bo…

Numerical Invariants and Parameter Recovery for Quasi-Homogeneous Submodules

Yin Liu, Yufeng Lu, Yixin Yang

We study Yang's higher numerical invariants for the quasi-homogeneous submodules \[ M_{k,\ell}=[z^k-w^\ell]\subset H^2(\mathbb D^2), \qquad k,\ell\in\mathbb N,\quad k\neq\ell. \] T…

Compactness of products and commutators of inner projections

Peiran Zhang, Roumei Tian, Yufeng Lu +2

In this paper, we study the compactness of the product and the commutator of two inner projections on the Hardy spaces over the unit disk and the polydisc. For the single-variable…

A geometric approach to the compressed shift operator on the Hardy space over the bidisk

Yufeng Lu, Yixin Yang, Chao Zu

This paper studies the compressed shift operator on the Hardy space over the bidisk via the geometric approach. We calculate the spectrum and essential spectrum of on t…
