Oh! Yeah, I think that is it. The nearest-neighbour distance. I got everything confused.

comment Average distance between random points inside a cube
I am still confused about where the concentration of points enter. I mean, if $n$ is large, than the average distance between them should be smaller, but I don't see how that enters the calculation. Anyway, thank you for the help.

comment Solving for the trace of a matrix
I have come across that manipulation but, unfortunately, it does not remove $\Theta$ so it doesn't really work much. But, in any case, thanks for your help.

@Berci the matrix $\Theta$ is uniquely determined from the Lyapunov equation. Hence so is $F$.

Good Point. :) Once again, thank you.

comment Discrete Analogue of the Fundamental Theorem of Calculus
I see. But isn't this notation misleading? I mean, in continuous calculus you write $d/dx$ to specify the derivative is with respect to $x$. Wouldn't $\Delta_n$ be a more adequate notation? And is this common in difference calculus literature? Anyway, thank you very much for the answer.
