Uniformization

Definition

Uniformization refers to the process of transforming a non-uniform collection of mathematical objects into a uniform one, typically through the extraction of a single function or rule that applies uniformly across a specific domain. This concept is important for understanding how to refine proofs and ensure that certain parameters are consistent throughout, especially in the context of proof mining and proof unwinding, where the goal is to extract constructive content from non-constructive proofs.
