# 2024 CMS Summer Meeting Mini-Courses: Applied Topology: Persistent Homology

## Topic

Applied Topology: Persistent Homology

## Details

Persistent Homology is an application of algebraic topology (filtered chain complexes) to statistics. Roughly speaking, one naturally associates filtered chain complexes to data in a variety of ways. Persistent homology is the structure of how the homology changes as the filtration evolves. Homology classes that exist for `long' or `big' regions in the filtration are deemed more significant than ones that exist for shorter or smaller periods. Research in persistent homology centres around issues such as 1) efficient computation for various filtration types, parallelization, etc, 2) theoretical significance of computations: stability or lack of it, and the ability to infer structure in the underlying data from computations, noise vs. signal.

###### The mini-course on Persistent Homology will be structured as follows:

- Discussion of motivating examples and basic ideas from algebraic topology: homology, manifolds, Steenrod realization.
- A sampling of a few different filtered chain complex types. Computation of persistent homology. Computer examples.
- Basics of the theory: computational complexity, stability, signal vs. noise theorems, asymptotics.
