Perturbation Theory

History and Overview 2022-12-15 v1

Abstract

This article aims to explain essential elements of perturbation theory and their conceptual underpinnings. It is not meant as a summary of popular perturbation methods, though some illustrative examples are given to underline the main methodological insights and concerns. We also give brief explications of the mathematical notions of limit, continuity, differentiability, convergence, and divergence, which provide the necessary foundation.
