{wiki=Simply_connected_at_infinity}
In topology, a space is said to be simply connected if it is path-connected and every loop (closed path) in the space can be continuously contracted to a single point. When the term "at infinity" is used, it generally refers to the behavior of the space as we consider points that are "far away" or tend toward infinity.
