Course objectives
The goal of this lecture is to give basic background of ideas and principles of modern cosmology to interested students that will be able to perform their own study and research of this part of theoretical physics where general relativity overlaps quantum field theory.
Learning outcomes
Students acquire basic ideas and principles of modern cosmology and will be able to perform their own study and research of this part of theoretical physics where general relativity overlaps quantum field theory.
