Analytic Besov functional calculus for several commuting operators

Abstract

This paper investigates analytic Besov functions of $n$ variables which act on the generators of $n$ commuting $C_0$-semigroups on a Banach space. The theory for $n=1$ has already been published, and the present paper uses a different approach to that case as well as extending to the cases when $n\ge 2$. It also clarifies some spectral mapping properties and provides some operator norm estimates.
