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.
