Analytic methods

Definition

Analytic methods refer to mathematical techniques and tools used to analyze and solve problems within the context of differential topology and critical point theory. These methods allow for the precise study of the behavior of functions, especially when examining their critical points, which is central to understanding the implications of the Morse Lemma. They provide insights into the local structure of manifolds and facilitate the identification of topological features through calculus-based approaches.
