Multiple operator integrals and higher operator derivatives
V. V. Peller
In this paper we consider the problem of the existence of higher derivatives of the function $t\mapsto\f(A+tK)$, where $\f$ is a function on the real line, is a self-adjoint op…

Approximation by analytic operator functions. Factorizations and very badly approximable functions
V. V. Peller, S. R. Treil
This is a continuation of our earlier paper \cite{PT3}. We consider here operator-valued functions (or infinite matrix functions) on the unit circle $\T$ and study the problem of a…

An extension of the Koplienko-Neidhardt trace formulae
Vladimir Peller
Koplienko [Ko] found a trace formula for perturbations of self-adjoint operators by operators of Hilbert Schmidt class $\bS_2$. A similar formula in the case of unitary operators w…
