WebSection 2.3 Limit superior, limit inferior, and Bolzano–Weierstrass. Note: 1–2 lectures, alternative proof of BW optional. In this section we study bounded sequences and their subsequences. In particular, we define the so-called limit superior and limit inferior of a bounded sequence and talk about limits of subsequences. WebProperty) to prove the Bolzano–Weierstrass Theorem. For this prob-lem, do the opposite: use the Bolzano–Weierstrass Theorem to prove the Axiom of Completeness. Proof. This will follow in two parts. Lemma 0.1.

Webpoint in K. [Bolzano-Weierstrass] Proof Say no point of K is a limit point of E. Then each point of K would have a neighborhood containing at most one point q of E. A finite number of these neighborhoods cover K – so the set E must be finite. Theorem 2.41 Let {E ∈ Rk}. The following properties are equivalent: (a) E is closed and bounded.
