After first reviewing the Big Bang theory, the instructor will point out problems with the theory, and explain how inflation resolves those problems. Then the instructor will explain models and dynamics of inflation, the production mechanism of density fluctuations and primordial gravitational waves produced in inflation, and their properties.
The goal is to understand the basics of inflationary cosmology.
[Objectives] This course will cover inflation cosmology, which is a history of the early universe, inflation theory, and students will gain an understanding of the properties of primordial fluctuations generated in that epoch.
[Topics] This course will cover the idea of inflation, the actual model and dynamics, linear perturbation theory for representing fluctuations of the universe, and the production mechanisms for primordial fluctuations.
