A set S of real numbers is called bounded from above if there exists some real number k (not necessarily in S) such that k ≥ s for all s in S. The number k is called an upper bound of S. The terms bounded from below and lower bound are similarly defined. A set S is bounded if it has both upper and lower bounds. Therefore, a set of r… WebIn other words, the union of any collection of open sets is open. [Note that Acan be any set, not necessarily, or even typically, a subset of X.] Proof: (O1) ;is open because the condition (1) is vacuously satis ed: there is no x2;.

By the same proof, any convex set in a normed space is connected. In particular, E n and all other normed spaces are connected themselves. http://www.u.arizona.edu/~mwalker/econ519/Econ519LectureNotes/Open&ClosedSets.pdf cimb bank business units

WebIf a set is closed and bounded, then it is compact. If a set S in R n is bounded, then it can be enclosed within an n-box = [,] where a > 0. By the lemma above, it is enough to show that T 0 is compact. Assume, by way of contradiction, that T 0 is not compact. Then there exists an infinite open cover C of T 0 that does not admit any
