Enrico Pajer - Lectures on Theoretical Physics

An introduction to Cosmology for master and graduate students (Part III of the Math Tripos).

An introduction to Field Theory methods for the Cosmology of the very early universe for master and graduate students (Part III of the Math Tripos).

These notes are based on the lectures I gave at the 2019 Asian-Pacific Winter School hosted by the Yukawa Institute of Theoretical Physics in Kyoto, Japan.
