Modified gravity models play an important role in contemporary theoretical cosmology. The present book proposes a novel approach to the topic based on techniques from noncommutative geometry, especially the spectral action functional as a gravity model. The book discusses applications to early universe models and slow-roll inflation models, to the problem of cosmic topology, to non-isotropic cosmologies like mixmaster universes and Bianchi IX gravitational instantons, and to multifractal structures in cosmology.

Relations between noncommutative and algebro-geometric methods in cosmology is also discussed, including the occurrence of motives, periods, and modular forms in spectral models of gravity.

Contents:

  • Preface
  • Acknowledgments
  • Gravity and Matter in Noncommutative Geometry
  • Renormalization Group Flows and Early Universe Models
  • Cosmic Topology
  • Algebro-geometric Models in Cosmology
  • Mixmaster Cosmologies
  • The Spectral Action on Bianchi IX Cosmologies
  • Motives and Periods in Cosmology
  • Fractal and Multifractal Structures in Cosmology
  • Noncommutative Quantum Cosmology
  • Bibliography
  • Index

Readership: Graduate students and researchers in mathematical physics and theoretical cosmology.
Key Features:

  • While there are recent books that focus on applications of noncommutative geometry to particle physics models, there is presently no other book that focuses on applications to cosmology
