Unlocking Decision Power: How the Perron‑Frobenius Theorem Drives AHP

This article explains the Perron‑Frobenius theorem, its role in analyzing positive and non‑negative matrices, and how it underpins the Analytic Hierarchy Process by ensuring unique dominant eigenvalues and eigenvectors, with examples ranging from decision‑making to Markov chains, population models, and PageRank.

How the Keener Method Quantifies Team Strength Using Eigenvectors

The Keener method assigns numerical ratings to competing teams by linking each team's score to its absolute strength, which depends on relative strength against opponents, and uses linear‑algebraic techniques such as eigenvectors and the Perron‑Frobenius theorem to derive consistent rankings.
