Abstract:
The main result of this paper is a description of the space of functions on the unit circle, for which Krein's trace formula
holds for arbitrary pairs of unitary operators with trace class difference. This space coincides with the space of operator Lipschitz functions on the unit circle.
Keywords:
Krein's trace formula, spectral shift function, operator Lipschitz functions, double operator integrals, Schur multipliers.
