Über dieses Buch

The focus program on Analytic Function Spaces and their Applications took place at Fields Institute from July 1st to December 31st, 2021. Hilbert spaces of analytic functions form one of the pillars of complex analysis. These spaces have a rich structure and for more than a century have been studied by many prominent mathematicians. They have essential applications in other fields of mathematics and engineering. The most important Hilbert space of analytic functions is the Hardy class H2. However, its close cousins—the Bergman space A2, the Dirichlet space D, the model subspaces Kt, and the de Branges-Rovnyak spaces H(b)—have also garnered attention in recent decades. Leading experts on function spaces gathered and discussed new achievements and future venues of research on analytic function spaces, their operators, and their applications in other domains.
With over 250 hours of lectures by prominent mathematicians, the program spanned a wide variety of topics. More explicitly, there were courses and workshops on Interpolation and Sampling, Riesz Bases, Frames and Signal Processing, Bounded Mean Oscillation, de Branges-Rovnyak Spaces, Blaschke Products and Inner Functions, and Convergence of Scattering Data and Non-linear Fourier Transform, among others. At the end of each week, there was a high-profile colloquium talk on the current topic. The program also contained two advanced courses on Schramm Loewner Evolution and Lattice Models and Reproducing Kernel Hilbert Space of Analytic Functions.
This volume features the courses given on Hardy Spaces, Dirichlet Spaces, Bergman Spaces, Model Spaces, Operators on Function Spaces, Truncated Toeplitz Operators, Semigroups of weighted composition operators on spaces of holomorphic functions, the Corona Problem, Non-commutative Function Theory, and Drury-Arveson Space. This volume is a valuable resource for researchers interested in analytic function spaces.

Chapter 1. Hardy Spaces
Javad Mashreghi
Chapter 2. The Dirichlet Space
Abstract
The notes below are a copy of a set of three lectures presented online in July 2021, during the Fields Institute Focus Program Analytic Function Spaces and their Applications. I am grateful to the Fields Institute and to the organizers of the Focus Program for the opportunity to present these talks.

Chapter 3. Bergman Space of the Unit Disc
Stefan Richter
Chapter 4. Model Spaces
Stephan Ramon Garcia
Chapter 5. Operators on Function Spaces
Abstract
This is a set of lecture notes to accompany a series of talks given as part of the Fields Institute session on Operators on Function Spaces from July–December 2021. These notes are also part of a book project by myself, Stephan R. Garcia, and Javad Mashreghi titled Operator Theory by Example (Oxford University Press). Many of the technical details as well as other examples of operators on function spaces can be found there.
William Ross
Chapter 6. Truncated Toeplitz Operators
Abstract
Truncated Toeplitz operators are compressions of Toeplitz operators on model spaces; they have received much attention in the last years. This survey article presents several recent results, which relate boundedness, compactness, and spectra of these operators to properties of their symbols. We also connect these facts with properties of the natural embedding measures associated to these operators.
Emmanuel Fricain
Chapter 7. Semigroups of Weighted Composition Operators on Spaces of Holomorphic Functions
Isabelle Chalendar, Jonathan R. Partington
Chapter 8. The Corona Problem
Abstract
The chapter provides an introduction into the area of the corona problem for bounded holomorphic functions.
Alexander Brudnyi
Chapter 9. A Brief Introduction to Noncommutative Function Theory
Abstract
This survey provides a very brief introduction to the notion of a noncommutative function, with a particular emphasis on those parts of the theory which are inspired by or related to the classical theory of Hilbert function spaces.
Michael T. Jury
Chapter 10. An Invitation to the Drury–Arveson Space
Abstract
This is an extended version of a three part mini course on the Drury–Arveson space given as part of the Focus Program on Analytic Function Spaces and their Applications, hosted by the Fields Institute and held remotely. The Drury–Arveson space, also known as symmetric Fock space, is a natural generalization of the classical Hardy space on the unit disc to the unit ball in higher dimensions. It plays a universal role both in operator theory and in function theory. These notes give an introduction to the Drury–Arveson space.
