Differentiability of functions of contractions

V. V. Peller

In this paper we study differentiability properties of the map $T \mapsto ϕ (T)$ , where $ϕ$ is a given function in the disk-algebra and $T$ ranges over the set of contractions on Hilb…

Analytic approximation of matrix functions in $L^{p}$

L. Baratchart, F. L. Nazarov, V. V. Peller

We consider the problem of approximation of matrix functions of class $L^{p}$ on the unit circle by matrix functions analytic in the unit disk in the norm of $L^{p}$ , $2\le p<\be$. For…

Analytic approximation of matrix functions and dual extremal functions

V. V. Peller

We study the question of the existence of a dual extremal function for a bounded matrix function on the unit circle in connection with the problem of approximation by analytic matr…
