We construct two bounded functional calculi for sectorial operators on Banach spaces, which enhance the functional calculus for analytic Besov functions, by extending the class of functions, generalizing and sharpening estimates, and adapting the cal

Motivated by applications to renewal theory, Erdős, de Bruijn and Kingman posed a problem on boundedness of reciprocals (1−z)/(1−F(z)) in the unit disc for probability generating functions F(z). This problem was solved by Ibragimov in 1975 by co

We introduce new techniques allowing one to construct diagonals of bounded Hilbert space operators and operator tuples under “Blaschke-type” assumptions. This provides a new framework for a number of results in the literature and identifies (ofte

We identify subsets of the joint numerical range of an operator tuple in terms of its joint spectrum. This result helps us to transfer weak convergence of operator orbits into certain approximation and interpolation properties for powers in the unifo

We extend and deepen the theory of functional calculus for semigroup generators, based on the algebra $\mathcal B$ of analytic Besov functions, which we initiated in a previous paper. In particular, we show that our construction of the calculus is op

We obtain integral representations for the resolvent of $\psi(A)$, where $\psi$ is a holomorphic function mapping the right half-plane and the right half-axis into themselves, and $A$ is a sectorial operator on a Banach space. As a corollary, for a w

We construct a new bounded functional calculus for the generators of bounded semigroups on Hilbert spaces and generators of bounded holomorphic semigroups on Banach spaces. The calculus is a natural (and strict) extension of the classical Hille-Phill

We prove that for any Bernstein function ψ the operator − ψ ( A ) generates a bounded holomorphic C 0 -semigroup ( e − t ψ ( A ) ) t ≥ 0 on a Banach space, whenever −A does. This answers a question posed by Kishimoto and Robinson. Moreover
