Aug 9, 2011 at 14:27 comment added Gerald Edgar and no, $\delta$-fine means: $|x_{i+1}-x_{i}| \le \delta(\xi_i)$.
Aug 9, 2011 at 14:24 comment added Gerald Edgar In the closed version of the question, Emil Jeřábek says: ... I think that the intended definition of HK-equi-integrability should read: for every $\epsilon>0$ there exists a gauge $\delta$ such that for every $n$ and every $\delta$-fine partition $\mathcal P$, $|S(f_n,\mathcal P)−\int f_n|\le \epsilon$.
Aug 9, 2011 at 13:26 comment added Pietro Majer Oh I didn't notice all these clones of the question.
Aug 9, 2011 at 13:23 comment added Pietro Majer no special point, but to have a clear question.

Aug 9, 2011 at 12:06 comment added Emil Jeřábek This question is a duplicate (slightly expanded) of mathoverflow.net/questions/72447 . @Pietro: The whole question is about Henstock–Kurzweil integral. What would be the point of asking $f_n$ to be Riemann integrable?
Aug 9, 2011 at 11:37 comment added Pietro Majer Please confirm: 1) The $f_n$ are assumed Riemann integrable. 2) Here the norm $\|\cdot\|_X$ is just the absolute value. 3) Here $\delta$-fine means $x_{i+1}-x_i\le \delta(\epsilon)$ for $i=0,\dots, n-1$.
