Limits of functions and sequences

[mathwonk]

excellent point! you are quite right that one should consider also possibly reducible curves, but i tend to think of irreducible ones. So, good point well taken, a closed subset of a reducible curve may not be finite, it might be a whole component! so maybe add "irreducible" to my statements about curves.

but i tend to think of irreducible ones.

I think this makes a lot of sense, given your background.

Thank you, and also @WWGD, for the little discussion.
