Simply connected space — In topology, a topological space is called simply connected (or 1 connected) if it is path connected and every path between two points can be continuously transformed, staying within the space, into any other path while preserving the two… … Wikipedia
Simply connected at infinity — In topology, a branch of mathematics, a topological space X is said to be simply connected at infinity if for all compact subsets C of X , there is a compact set D in X containing C so that the induced map: pi 1(X D) o pi 1(X C),is trivial.… … Wikipedia
Locally simply connected space — In mathematics, a locally simply connected space is a topological space that admits a basis of simply connected sets. Every locally simply connected space is also locally path connected and locally connected.The circle is an example of a locally… … Wikipedia
Timelike simply connected — Suppose a Lorentzian manifold contains a closed timelike curve (CTC). No CTC can be continuously deformed as a CTC (is timelike homotopic) to a point, as that point would not be causally well behaved. Therefore, any Lorentzian manifold containing … Wikipedia
