Typo's , mistakes and confusion should be gone.

Although the convergeance conjecture disagrees with sheldon's recent not 1 ratio ... Maybe ...

Things should be clear now.

Start with

g''(x) for f(x) is conjectured to approach exactly g''(x) for J(x), as x gets arbitrarily large, which is the initial reason for choosing this particular f(x). But f(x) is interesting on its own.

I generate the fake function for f(x) using the Gaussian method. I assume that this is what Tommy means in post#150 by F_2(x).
> F_2(x) = F_1(x) • sqrt( 2 pi G_1 '' (h_n) )

where for f(x) optionally
Is this the same as Tommy's F_2? Tommy has the g'' in the numerator which is a typo. It looks like Tommy's F_3 would be the fake function for F_2(x)? I'm not sure if that's what Tommy intended or not.

f2(x) is the fake Gaussian approximation for f(x)

Now, starting with let's generate
From there, we can generate a new set of values, which should be nearly identical to the original set of h_n values, and a new set of values which should be nearly identical to the values.

I did this numerically. I think I might be able to generate a closed form equation for this new ratio result, using the equations from post#85. I guess this ratio not going to a limiting value of 1 is a contradiction for your conjecture. Its actually rather interesting, especially if you consider the ratio for non integer values of a_n; n=20.5; vs the equation above. I can post more later if interested; it turns out we have a sine wave oscillating around Anyway, assuming g''(x) for f(x) is asymptotically the same as g''(x) for J(x) as x gets arbitrarily large, I expect the limiting ratio for J(x) to be the same as the limiting ratio below, as n gets arbitrarily large.

Wait.

If a_n ~~ exp(g(h_n) - n h_n)

Is An underestimate ( as you say )

And the gaussian is beter then

Gaussian > exp( g(h_n) - n h_n).

Right ?

So gaussian can not be exp ... / sqrt( 2 pi g" (h_n)).

It has to be exp( g(h_n) - n h_n) * sqrt( 2 pi g " (h_n) ).

Or am I crazy today ?
