Spectral dynamics for the infinite dihedral group and the lamplighter group

Chao Zu, Yixin Yang, Yufeng Lu

For a tuple $A = (A_{0}, A_{1}, \dots, A_{n})$ of elements in a Banach algebra $B$ , its projective (joint) spectrum $p (A)$ is the collection of $z \in P^{n}$ such that $A(z)…

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 $S_{z}$ on the Hardy space over the bidisk via the geometric approach. We calculate the spectrum and essential spectrum of $S_{z}$ on t…
