Perturbation theory comprises mathematical methods that are used to find an approximate solution to a problem that cannot be solved exactly, by starting from the exact solution of a related problem.
Perturbation Methods at Rensselaer
Researchers study regular and singular perturbation theory to systematically construct an approximation of the solution of a problem that is otherwise intractable.
Researchers are currently working on:
- Regular perturbation theory.
- Singular perturbation theory.
- Computational methods for singularly perturbed problems.
