The mean transform and the mean limit of an operator

F. Chabbabi, E. Curto, M. Mbekhta

Let $T$ be a bounded linear operator on a Hilbert space $H$ , and let $T \equiv V ∣ T ∣$ be the polar decomposition of $T$ . The mean transform of $T$ is defined by $\widehat{…

Compressions of Resolvents and Maximal Radius of Regularity

C. Badea, M. Mbekhta

Suppose that $λ - T$ is left-invertible in $L (H)$ for all $λ \in Ω$ , where $Ω$ is an open subset of the complex plane. Then an operator-valued function $L (λ)$ is a left resolvent of…
