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. WebbAssume that Dis not simply connected (thus D6=C). Since D is not simply connected it follows by de nition of simply connected that there exists a closed path in Dthat is not homotopic to a point. So there must exist at least one point sin the region enclosed by which is not contained in D. So it then follows that sand 1lie in di erent connected ... saying food funny https://shipmsc.com
