Perturbation Expansion

Perturbation Expansion is a mathematical technique within asymptotic analysis that distinguishes itself by expressing a solution to a problem as a series expansion in terms of a small parameter, where each term in the series accounts for progressively higher-order effects of a perturbation to an exactly solvable base problem.
