It only takes a minute to sign up. We have an $l_p$ space $W$. My thoughts were $d(L,x^n)\leq d(L,x^{m+i})+d(x^{m+i},x^n)$. rev 2020.9.25.37676, The best answers are voted up and rise to the top, Mathematics Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us.

However, I don't know how to make $d(L,x^{m+i})$ arbitrarily small. Use MathJax to format equations. If you want to discuss contents of this page - this is the easiest way to do it. Append content without editing the whole page source. I know complete means that every cauchy sequence is convergent. Watch headings for an "edit" link when available. So, I am given a metric space. I'm trying to prove $l_p$ spaces are complete. Every compact metric space is complete, though complete spaces need not be compact.

A metric space (X,d) is said to be complete if every Cauchy sequence in X converges (to a point in X). What happens if ground and neutral are swapped in a light switch?

Now we’ll prove that R is a complete metric space, and then use that fact to prove that the Euclidean space Rn is complete.

Then $C^0 (X,Y)$ is complete under the uniform convergence metric.

ALso, let $L=\{l_1,l_2,l_3,\dots\}$. Indeed, a space is complete if and only if it is closed in any containing metric space.

Is "calendula paddle" used in the literal sense in "The Liar's Key"? Let us come back to $d(x^m,x^n)$. Something does not work as expected? This implies $\left (|x_1^m-x_1^n|^p + |x_2^m-x_2^n|^p+\dots\right)^{\frac{1}{p}}<\epsilon$.

If it is, how?
