Abstract
In this lecture, we will study contractible 3-manifolds and its relationship with positive scalar curvature. For example, Whitehead manifold is a contractible 3-manifold, but not homomorphic to 3-dimensional Euclidean space. We will give a proof that Whitehead manifold does not have a a complete metric with positive scalar curvature.
Lecture 1: We will focus on the construction of contractible 3-manifold and its topological properties. Particularly, we will describe the topology at infinity of contractible 3-manifolds and its relationship with knot theory.
Lecture 2: We will study the existence of positive scalar curvature metric on contractible 3-manifold. Especially, we will talk about how positive scalar curvature effects the topology at infinity.
