This edited volume offers a state of the art overview of fast and robust solvers for the Helmholtz equation. The book consists of three parts:

new developments and analysis in Helmholtz solvers, practical methods and implementations of Helmholtz solvers, and industrial applications.

The Helmholtz equation appears in a wide range of science and engineering disciplines in which wave propagation is modeled. Examples are: seismic inversion, ultrasone medical imaging, sonar detection of submarines, waves in harbours and many more. The partial differential equation looks simple but...
