Another new article: sequence space. I await the inevitable report that this term is also used for other things.
You certainly use the term in the way I expected, but I take issue with the statement “The name ‘sequence space’ is not often encountered”. Personally, I encounter that name all the time
I have added a link to the entry from the “Important subclasses”-section at topological vector space, but probably this deserves to be listed more systematically. Somehow.
I added the synonym for .
I entirely don’t get the point about versus . The definitions seem to me to be word-for-word identical. (Am I missing some tiny change?) It says “two different ways of thinking about the same thing”, but I see literally no difference apart from the change of name.

Good, maybe it is not such an obscure name, just left out of my education.

One way is as the culmination of the sequence , the other way is as the culmination of the sequence . Note that when we generalise from a set to a non-discrete space (and start using capital letters for some reason), the two notions diverge. (I’ll add something about this to the article.)
To paraphrase something I once heard in a talk, the name “sequences spaces” is well-known, in the usual sense of “well-known among those who know it well”.
Thanks for the clarification, Toby. I sort of see the point, but the trouble is that I don’t see in any precise sense what progression is happening in the sequence . So what you’ve written is almost as mysterious to me as if it had been the following:
We write for the category of abelian groups: for all and . […] We write for the category of abelian groups: for all and . Indeed, , two different ways of thinking about the same thing. (But they generalise differently.)
Would that make more sense if, later in the article, there was a section on generalisations where they did indeed generalise differently?
Not sure. It’s probably best to just ignore me and carry on. It was only a niggle anyway.
