Regular Perturbation Theory

Regular Perturbation Theory is a mathematical approach within perturbation methods that systematically approximates solutions to problems by expanding them in power series of a small parameter, where the leading-order term corresponds to an exactly solvable unperturbed system and higher-order corrections are obtained recursively without altering the fundamental structure of the underlying equations.
