Function Spaces and Their Operators
A Conference in Honor of Richard Rochberg on the Occasion of his 65th Birthday

Nigel Kalton from the University of Missouri, Columbia; Differential methods in interpolation; May 29, 2008.

Abstract: We will survey some applications of differential or commutator methods in interpolation theory as pioneered by Rochberg and Weiss in 1983. We will explain connections with the homological theory of Banach spaces, harmonic analysis and operator theory.
