29 окт. 2015 г. · To prove that your sequence is bounded, you must find a x∈X and a r>0 such that for all n∈N, d(an,x)<r (or ≤r, that is an equivalent statement). In a metric space, is every convergent sequence bounded? Every convergent sequence $(x_n)$ is bounded in $(M,d) Bounded sequence in metric space has convergent subsequence Другие результаты с сайта math.stackexchange.com |
