Dec 7, 2023 at 23:07 | comment | added | Willie Wong | @LSpice: Steven's wish (about advanced texts), but he is the post author so always gets notified. You were pinged also because of unordered infinite sums. | |
Dec 7, 2023 at 16:14 | comment | added | LSpice | @WillieWong, re, which witch wished which wicked wish? That is to say, whose wish? | |
Dec 7, 2023 at 3:01 | comment | added | Willie Wong | Your wish (wasn't) my command. And yes, unordered infinite sums are dealt with too. @LSpice | |
Nov 11, 2021 at 2:21 | comment | added | LSpice | Another example: the unordered sum $\sum_{x \in S} f(x)$ as a limit over the net of finite subsets $\lim_{F \subseteq S} \sum_{x \in F} f(x)$. | |
Jul 17, 2017 at 18:43 | comment | added | Todd Trimble | Steven -- oh of course. But if one should be teaching topology, it's a good example to keep in mind! | |
Jul 17, 2017 at 18:35 | comment | added | Steven Gubkin | @ToddTrimble Me either! Although that is a bit more structure than the typical calculus class probably wants to dive into. I am surprised that I have not seen this definition as part of more advanced texts though. | |
Jul 17, 2017 at 11:53 | comment | added | Todd Trimble | I don't think it's occurred to me before now that actually the Riemann integral is more naturally viewed as a limit of a net than as a limit of a sequence. | |
