Der anschauli che Begriff "Ankleben einer Zelle " lässt sich mit der kanonischen Projektion p: X U D " --+ X U f D " mathematis ch beschreiben: ple n bildet e" homöomorph auf p(e" ) ab. 26 Beispiele. (a) Sei X := D 2, 1 := ids l. Der Raum X Uf D2 ist eine 2-dim ension ale Sphäre. Vgl. Abb . 4 (a). ° (b) Sei X := {(x , y) E ]R2 I < x ~ 1,0 ~ y < I} , A := {(x ,y) E X I oder I} , Y := [0,1], und I : A --+ Y sei definiert durch I(O,y) = y , 1(1 , y) = 1 - y . Der Raum M := Y Uf X heißt Möbiusband.

Ist f: X -t Y stetig, so gilt: (a) Die Abbildungen p, J und j sind stetig. (b) J ist genau dann ein Homömorphismus, wenn das Bild jeder offenen (abgeschlossenen) Menge der Form f-1(A), Ac Y, offen (abgeschlossen) in f(X) ist. (c) Ist f: X -t Y außerdem surjektiv und offen oder abgeschlossen, so trägt Y die Identijizierungstopologie bezüglich f. Beweis. 3 stetig. Da f(X) die Initialtopologie bezüglich j trägt und f = j 0 J 0 p stetig ist, ist auch J 0 p stetig. Da XI", die Finaltopologie bezüglich p trägt, ist J stetig.

Bezeichnet [x] die größte ganze Zahl , die kleiner oder gleich x ist. Sei, < 1 eine positive irrationale Zahl. Die Abbildung I: Z -+ [0,1[, definiert durch n I-t n,- [n,] ist injektiv, und I(Z) liegt dicht in [0,1[. Wenn Z die diskrete Topologie trägt, ist I natürlich st etig, aber keine Einbettung. 2 (h , i) haben wir auf dem Produkt metrischer Räume (X, , d i ) , i E I , Metriken definiert , die auf den üblichen Einbettungen der Faktorräume in den Produktraum jeweils die ursprünglichen Metriken der Faktorräume eventuell bis auf einen konst anten Faktor genau - induzieren .
