WebThe closure of a connected set is also connected. Indeed, if Eis connected, consider its closure E and assume there exist nonempty sets Aand B such that E = A[B;and A\B= … WebNo. A counterexample is given by E = R nf0g= (1 ;0) [(0;1). The set is not connected since it is separated by the sets U = (1 ;0) and V = (0;+1). The closure of E is E = R since R is the only closed set containing E. Theorem 8.30 shows that R is connected, so we have found an example of a set E which is not connected, but has connected closure. 2

WebMar 24, 2024 · A connected set is a set that cannot be partitioned into two nonempty subsets which are open in the relative topology induced on the set. Equivalently, it is a set which cannot be partitioned into two nonempty subsets such that each subset has no points in common with the set closure of the other. Let be a topological space. WebProof.
