Power Stability of Finitely Generated Dynamical Frames for Positive Operators

Jian Wu

Let $ Λ=\{λ_j\}_{j\in\mathbb N}\subset[0,1) $ be a finite union of Carleson sequences, and let $ Λ^p=\{λ_j^p\}_{j\in\mathbb N} $ for $p>0$. We prove that $Λ$ and $Λ^p$ ad…

Boundary Rigidity and Classification of Spectral Transformations Preserving Frame Generators of Normal Diagonal Operator Orbits

Jian Wu

Let $C$ be the class of Carleson sequences in the unit disk $D$ . We study arbitrary maps $Φ : D \to D$ satisfying, for every sequence $Λ=\{λ_n\}_{n\ge1…
