Control and inverse problems in wave equations and graphs constitute a dynamic field at the intersection of applied mathematics, engineering and physics. This area investigates how waves propagating ...

Boundary Element Methods (BEM) have emerged as a robust numerical technique for addressing wave propagation problems across diverse fields such as acoustics, elastodynamics, and electromagnetics.

We describe some problems and results for formally determined (not over-determined) inverse (coefficient determination) problems for the perturbed wave equation. The problems have little geometry ...
