Fast-growing hierarchy

ID: fast-growing-hierarchy

The fast-growing hierarchy is a classification of functions based on their growth rates, typically used in mathematical logic and proof theory. It is a way to organize functions that grow faster than any computable function, providing a deeper understanding of the limits of computation and the nature of large numbers. The hierarchy is constructed using specific operations and is related to the *Buchholz hierarchy*, an extension of the * ordinals*.
