Title: A Geometrical Introduction to General Relativity
Abstract: In this talk, we give an introduction to general relativity
focusing on its geometrical aspects. We show how the curvature of
spacetime describes gravity through its warping of geodesics. The Einstein
equations will be discussed along with the Schwarzschild spacetime which
is a solution of the equations describing a black hole. Penrose's
singularity theorem will be presented along with its strengths and
weaknesses. We will then briefly review cosmology and discuss relevant
cosmological singularity theorems. Lastly, we will show how a class of k =
-1 inflationary FLRW spacetimes called "Milne-like" admit spacetime
extensions through the big bang.
