This self-contained introduction discusses the evolution of the notion of coherent states, from the early works of Schrödinger to the most recent advances, including signal analysis. An integrated and modern approach to the utility of coherent states in many different branches of physics, it strikes a balance between mathematical and physical descriptions.
Split into two parts, the first introduces readers to the most familiar coherent states, their origin, their construction, and their application and relevance to various selected domains of physics. Part II, mostly based on recent original results, is devoted to the question of quantization of various sets through coherent states, and shows the link to procedures in signal analysis.

Jean-Pierre Gazeau is professor of Physics at the University Diderot Paris 7, France, and a member of the ‘Astroparticles and Cosmology’ Laboratory (CNRS, UMR 7164). Having obtained his academic degrees from Sorbonne University and Pierre-and-Marie Curie University (Paris 6), he spent most of his academic career in Paris and, as invited professor and researcher, in many other places, among them UCLA, Louvain, Montreal, Prague, Newcastle, Rio de Janeiro and Sao Paulo. Professor Gazeau has authored more than 150 scientific publications in Theoretical and Mathematical Physics, mostly devoted to group theoretical methods in physics, coherent states, quantization methods, and number theory for aperiodic systems.
