Functional models for $Γ_{n}$ -contractions

Shubhankar Mandal, Avijit Pal, Bhaskar Paul

This article develops several functional models for a given $Γ_{n}$ -contraction. The first model is motivated by the Douglas functional model for a contraction. We then establish fac…

Infinite-dimensional features of matrices and pseudospectra

Avijit Pal, Dmitry V. Yakubovich

Given a Hilbert space operator $T$ , the level sets of function $Ψ_{T} (z) = ∥ (T - z)^{- 1} ∥^{- 1}$ determine the so-called pseudospectra of $T$ . We set $Ψ_{T}$ to be zero on the spectrum of…
