Urs created limit of a sequence on this topic.
We already had convergence space, which (in principle) covers convergence in all kinds of spaces (by describing their underlying convergence spaces). But it is better to give that topic it its own page (just as we have open subset as well as topological space).
I have long had vague plans to write this at convergence (which used to be a redirect to convergence space but now redirects to limit of a sequence). I would still put that forth as the best name for the page.
That makes sense. But I found that several entries mentioned “limits” in the sense of analysis/toplogy without pointing anywhere, which is why I created “limit of a sequence”. Only after I had created it did I see that we had “convergence space”.
But limit of a sequence is just a stub anyway. It is good to have such an entry which briefly states the idea. For detailed discussion it can point to “converegence space” and I think all will be good.
I added
Warning: if is not a Hausdorff topological space, there might be more than one point with the property that converges to . Then we say that the sequence converges to the set of all such points.
and created the entry series.
Thanks, good point.
More expansion of convergence.
