MATH20260 The Mathematics of Google

Academic Year 2023/2024

The module is designed to provide an introduction to applied linear algebra with an emphasis on topics used in large data analysis, and in particualar in Google search engine.

The Google search engine has made accessing information easy and its speed and efficacy amazes people. This module explains how it works. An essential component is the ability to rank information according to its importance, and in Google, this relies on simple algebraic principles. The mathematical areas involved are linear algebra and matrix analysis.

The presentation will in part be based on the book by Amy Langville and Carl Meyer "Google's PageRank and Beyond: The Science of Search Engine Rankings" (Princeton University Press 2006)
