Extended Abstracts Fall 2019

This book collects the abstracts of the mini-courses and lectures given during the Intensive Research Program "Spaces of Analytic Functions: Approximation, Interpolation, Sampling" which was held at the Centre de Recerca Matemàtica (Barcelona) in October-December, 2019.

The topics covered in this volume are approximation, interpolation and sampling problems in spaces of analytic functions, their applications to spectral theory, Gabor analysis and random analytic functions. In many places in the book, we see how a problem related to one of the topics is tackled with techniques and ideas coming from another.

The book will be of interest for specialists in Complex Analysis, Function and Operator theory, Approximation theory, and their applications, but also for young people starting their research in these areas.
