Simply connected region examples
Webb10 feb. 2024 · Some basic examples of a simply connected space are the unit disc in ℝ 2, S 2 or the Riemann sphere.Non-examples of a simply connected space are the circle, the annulus, and a punctured plane (a plane with a point removed).In each of the non-examples, any closed curve around the “hole” is a path that can not be shrunk to a point. WebbThe above definition applies to regions in a plane. It also applies to regions in space. The region shown in Fig.1 is simply connected. The region shown in Fig.2 is multiply …

WebbDef. Simply-connected region. A region R is said to be simply-connected if any simple closed curve which lies in R can be shrunk to a point without leaving R. A region R which is not simply-connected is said to be multiply-connected. The region shown in Fig. 1-1 is simply-connected. The regions shown in Figures 1-2 and 1-3 are multiply-connected.
