... connected set containing x that is, a (γ, γ 0 )-semi-θ-component of X. Uniqueness of the (γ, γ 0 )-semi-θ-component (containing x) is obvious. (2). Follows from (1). (3). By construction in (1), any (γ, γ 0 )-semi-θ-connected set is contained in the (γ, γ 0 )-semi-θ-component which contains any one ...

3-manifold
In mathematics, a 3-manifold is a space that locally looks like Euclidean 3-dimensional space. Intuitively, a 3-manifold can be thought of as a possible shape of the universe. Just like a sphere looks like a plane to a small enough observer, all 3-manifolds look like our universe does to a small enough observer. This is made more precise in the definition below.
