Perturbation Methods
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.
Current Projects
Researchers are currently working on:
 Regular perturbation theory.
 Singular perturbation theory.
 Computational methods for singularly perturbed problems.
