Modified Gravity: Unifying Inflation and Dark Energy

This lecture by the instructor focuses on the concept of modified gravity as a way to unify early time inflation with late time dark energy epoch. The discussion delves into the motivation behind studying modification of Einstein gravity, the different models of modified gravity such as F-R gravity and Scalar-Gauss-Bannett gravity, and the implications of these theories on cosmology, inflation, and dark energy. The lecture also explores the challenges and advantages of working with modified gravity theories, including the potential to describe dark matter and the unification of inflation, dark energy, and dark matter within a single framework.
