Resonances in Physics and Geometry

Maciej Zworski

For a broad range of phenomena, a state can be described by two parameters, rest energy and rate of decay. This information is encoded in a complex number whose real part is the energy and imaginary part is the rate of decay. Mathematically it appears as a pole of a natural meromorphic operator and is called a resonance. This article motivates the study of resonances and describes some recent advances in this study.
