Unbounded convergent sequence
Webweakly convergent and weak* convergent sequences are likewise bounded. Exercise 1.7. a. Show that weak* convergent sequences in the dual of a Banach space are bounded. Give an example of an unbounded but weak* convergence sequence in the dual of an incomplete normed space. Hint: The dual space of c00 under the ℓ∞ norm is (c00)∗ ∼= ℓ1. b. WebSolution 2. Show that (n2) is an unbounded sequence. It follows by a theorem we proved in class that (n2) is a divergent sequence. 3. Decide if each of the following sequences (a n)1 n=1 converges or diverges. If the sequence converges, state its limit. In either case, you must use the appropriate de nition or theorem to prove that the sequence

Web25 Mar 2015 · 1. If a sequence ( x n) converges it is bounded (you should proove it showing that every element except a finite number of them of the sequence is at distance at most … Webn) is unbounded. Is the converse true, that any divergent sequence is either unbounded or has two subsequences that converge to a di erent limit? We use the fact that a sequence (a n) is convergent to a limit lif and only if every subsequence of (a n) is convergent to the same limit l. Taking the negation of each side of this equivalence, we have:1
WebTheorem 1: Bounded Sequence Theorem. Every bounded sequence in $\R^n$ has a subsequence that converges to a limit. This is an excellent theorem if you like convergent sequences. It is also very useful for proving that certain kinds of problems (for example, minimization problems) have solutions, as we will see.
