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…

Contractivity and complete contractivity for finite dimensional Banach Spaces

Gadadhar Misra, Avijit Pal, Cherian Varughese

Choose an arbitrary but fixed set of $n \times n$ matrices $A_{1}, \dots, A_{m}$ and let $Ω_{A} \subset C^{m}$ be the unit ball with respect to the norm $\|\cdot\|_{\mathbf…
