Keep in mind, that is fixed point, id est,
I have to notice that I didn't deduced it but just observed the progression of your formulas on your book.
Anyways I tried to substitute YOUR solution inside the transfer equation ... but my deduction has some holes, I need some algebraic manipulation in order to come at your final form:
In fact developing I get



that looks very different from the series you show in your book at formula (6.4)

(6.4)

So the question is how one can go from TO ?

And how you can manipulate the series and obtain a series of the form
? In other words

I used Maple; then I found that it is not so good, http://en.wikisource.org/wiki/Maple_and_Tea
and Mathematica does this better.

In addition, I use C++ to plot graphics and the complex maps, and you can do the same. You may use my algorithms and codes, and you may write your own codes, it is better for your education. Keep in mind, that all codes have bugs.
If you get some tens coefficients with Mathematica and use them in the C++ code, the resulting implementation may return of order of 14 significant figures, and allow to plot the complex maps in the real time.
You may load the examples from

Try to write your own algorithms.
Run the tests.
Substitute the functions you get into the equations they are supposed to satisfy. Plot the residuals.
Compare your calculus to my calculus.
Try to make your algorithms more precise, than my ones.
Try to make your algorithms shorter and simpler, than my ones.
Try to make your algorithms faster, than my ones.
Try to make your algorithms more general, than my ones.

No I don't have powerful softwood and I don't even know how C++ works (I'd need a massive amount of time to learn it)

------------------

Other topic: With your supefunction formalism/metods/techniques(or theory or how you call it) is possible to find solution to factorial-like problems where there are involved families of different functions instead of only one function iterated many times? Consider this general problem
Given a family of functions we define a function such that it satisfies this equations





Is it possible to find an unique extensions of $H$ to the real/complex numbers?
This is a very general problem: if and then and its extension is the gamma function but we can still achieve uniqueness for other sequences of functions?

Thank you again for the kindness!

How many sample points are required for the Kouznetsov Cauchy integral method to get double precision (51 bits=16 decimal digits) accuracy? I seem to remember it was 1000-2000 sample points; also, how many iterations? Do you have any estimates on how fast the number of sample points required grows? For example, what it would take to get twice that precision, 32 decimal digits?
