The propagation of acoustic and electromagnetic waves in stratified media is a subject that has profound implications in many areas of applied physics and in engineering, just to mention a few, in ocean acoustics, integrated optics, and wave guides. See for example Tolstoy and Clay 1966, Marcuse 1974, and Brekhovskikh 1980. As is well known, stratified media, that is to say media whose physical properties depend on a single coordinate, can produce guided waves that propagate in directions orthogonal to that of stratification, in addition to the free waves that propagate as in homogeneous media. When the stratified media are perturbed, that is to say when locally the physical properties of the media depend upon all of the coordinates, the free and guided waves are no longer solutions to the appropriate wave equations, and this leads to a rich pattern of wave propagation that involves the scattering of the free and guided waves among each other, and with the perturbation. These phenomena have many implications in applied physics and engineering, such as in the transmission and reflexion of guided waves by the perturbation, interference between guided waves, and energy losses in open wave guides due to radiation. The subject matter of this monograph is the study of these phenomena.

This book gives its readers a unique opportunity to get acquainted with new aspects of the fruitful interactions between Analysis, Geometry, Quantum Mechanics and Number Theory. The present book contains a number of contributions by specialists in these areas as an homage to the memory of the mathematician Erik Balslev and, at the same time, advancing a fascinating interdisciplinary area still full of potential. Erik Balslev has made original and important contributions to several areas of Mathematics and its applications. He belongs to the founders of complex scaling, one of the most important methods in the mathematical and physical study of eigenvalues and resonances of Schrödinger operators, which has been very essential in advancing the solution of fundamental problems in Quantum Mechanics and related areas. He was also a pioneer in making available and developing spectral methods in the study of important problems in Analytic Number Theory.

The book will contain refereed articles by the invited speakers on the 2024 AMP conference to be held during August 5-17, 2024 online. AMP stands for Analysis and Mathematical Physics. It brings leading experts in their fields, delivering 1-hour lectures in their field of expertise. There are 28 invited speakers, and there will also be many participants attending the online conference without presenting talks. The conference will concentrate on the following topics: Inverse problems for nonlocal operators Orthogonal polynomials, Jacobi and CMV matrices Quantum graphs Applications of spectral and scattering theory to quantum mechanics and plasma physics Differential operators on closed sets Differential operators on spatial networks Direct and inverse spectral and scattering theory for differential and difference equations and for systems of such equations The aim of the conference is to bring together leading experts and young researchers from all over the world who work in the area of mathematical physics. It promotes exchange of ideas and develops future scientific collaborations and strengthens existing collaborations. The online conference will be broadcast live on a zoom webinar broadcast on Facebook and Youtube channels of IIMAS of UNAM. The list of the speakers and the details for the conference can be found at the conference webpage: https://www.iimas.unam.mx/amp2024/
