Lecture Notes in Cosmology (eBook, PDF)

• Format: PDF

Produktbeschreibung

Provides an in-depth introduction to cosmology for beginners including open problems and very recent topics such as the synchronicity problem

Functional appendices contain the necessary physics background as a reminder to students making the book self-contained

Exercises in the text complete the derivations of the results, whose ideas and logical steps are carefully outlined
