NONCOMMUTATIVE COSMOLOGY

Focusing on modified gravity models, this book introduces a unique approach utilizing noncommutative geometry, particularly the spectral action functional. It explores applications in early universe scenarios, slow-roll inflation, cosmic topology, and non-isotropic cosmologies such as mixmaster universes and Bianchi IX gravitational instantons. Additionally, it delves into the implications of multifractal structures in cosmology, offering a comprehensive examination of contemporary theoretical frameworks in the field.
