Edelsbrunner, Letscher and Zomorodian: topological persistence

What changed

Topological structure became computable across scales as a persistence quantity.

Scientific scope

Exact three-author 2002 paper; later diagrams, stability theorems and TDA applications excluded.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact 2002 Discrete & Computational Geometry paper. Earlier persistence ideas, later persistence diagrams and stability theorems, software implementations and the broader field of topological data analysis remain separate.
