Singular perturbation
ID: singular-perturbation
Singular perturbation refers to a situation in mathematical analysis, particularly in the study of differential equations, where a small parameter multiplies the highest derivative in the equation. This small parameter can lead to significant changes in the behavior of the solution, resulting in phenomena that cannot be understood by analyzing the equation without this parameter. In this context, singular perturbations typically give rise to boundary layers — regions where the solution changes rapidly compared to other regions.
