 Persistent homology group

Persistent homology is a concept from computational topology, a branch of mathematics that studies the shape, structure, and features of data. It provides a way to analyze the topology of data sets, particularly those that vary with a parameter, by examining how the topological features of a shape persist across different scales. ### Key Concepts of Persistent Homology: 1. **Topological Spaces and Chains**: - Topological spaces are sets equipped with a structure that allows for the concept of continuity.
