Comment Spectral Methods & Perturbations (Score 1) 260
You might take a look at what some of the astrophysics people are doing. At Northwestern they were using spectral methods to study the environment near event horizons.
In my own research modeling systems of laser cavities, non-linear absorbers/emitters and so forth, it was sometimes useful to start with the system and add the obstacle through a perturbation.
