84: 74: 53: 2612:. Currently the article has two self-contained sections about two relatively distinct subjects, both of which would seem to be worthwhile subjects for articles of their own. There seems to be no reason for this other than inertia. The current referencing style makes in unclear which source corresponds to which subject, so the references would reviewed to see which article they should be placed in.-- 22: 2507:"relationship between differentiation and integration is commonly characterized in the framework of Riemann integration" — I think, it means that, having a continuously differentiable function, you can restore it from its derivative by Riemann integration. Poor English? Do you prefer "described" instead of "characterized"? Propose your formulation. 743: 1761: 2664:
Today, I made what should have been a very small (one character) edit to the bit on R-N theorem. I apologise that it took me 4 attempts to get mu and nu the correct way around in the text of my accompanying edit summary. Hence the multiple undos and redos whose sole purpose was to correct the edit
2627:
No, I believe, these two notions are very much related (as written in Sect.2.1). The sources could be better; I'll add more sources soon. And they will be sources that do describe both subjects (and their relation). True, the relation becomes weak when we turn to functions with values in metric

The Generalizations section discusses functions whose range is a general metric space, but the domain is still the real line. Is there a standard way to generalize absolute continuity to functions whose domain is a general metric space, or at least a multi-dimensional space? E.g., when does a

I am not too familiar with absolute continuity but it seems a little odd that it should be stronger than Lipschitz, as the lead paragraph currently claims. Could someone add a clarification?
2467:
This page ought to have some mention of the Lebesgue version of the Fundamental Theorem of Calculus. To my mind that's a major reason for being interested in absolutely continuous functions.

Really, here "locally" is not needed, since the measure is assumed to be finite. (Otherwise, "locally" is needed, and means: on every bounded interval.)

Is the sentence "This relationship is commonly characterized ...." in the first paragraph correct (English)? I can't understand what does it means.

Hi Boris. What you say is correct. I was tryin' to say that these are examples which are not absolutely continuous

And no wonder. Given a divergent series, no matter how far is its tail, you can find an infinite sum in the tail.
