Abstract

A Gabor system is a set of time-frequency translates of a given function in the Hilbert space \(L^2(\mathbb{R})\) of square-integrable functions on the real line. In this talk I will give an introduction to Gabor systems and their spanning properties, which forms a ubiquitous part of time-frequency analysis. I will also present some joint work with Jakobsen, Luef and Omland on Gabor frames on locally compact abelian groups.
