That's a very deep question, Catullus. I honestly don't know the answer to it.

But to point out, when you use \(1 \le \alpha \le \eta\), you have a very fine growth in the hyper-operations. In that, they tend to \(\alpha\) for \(\Re(z) > 0\). So doing this in this interval is about the closest I ever got. Where, as I've written before, I'll write again.

\[

\vartheta(w,u) = \sum_{n=0}^\infty\sum_{k=0}^\infty \alpha \uparrow^{n+2} (k+1)\frac{u^nw^k}{n!k!}\\

\]

If we differentiate repeatedly in \(w\), we get:

\[

\frac{d^j}{dw^j} \vartheta(w,u) \approx e^w\sum_{n=0}^\infty \omega_{n+2} \frac{u^n}{n!}\\

\]

Where \(\omega_{n+2} = \alpha \uparrow^{n+2} \infty\), which are the fixed points of \(\alpha \uparrow^{n+1} z\). And if we differentiate repeatedly in \(u\), we get:

\[

\frac{d^l}{du^l} \vartheta(w,u) \approx \alpha e^{w}e^{u}\\

\]

Now as asymptotic limits, both of these things are differintegrable. Whereby:

\[

\frac{d^{s}}{du^{s}} \frac{d^{z}}{dw^z}\Big{|}_{u=0,w=0} \vartheta(w,u) = \alpha \uparrow^{s+2} z+1\\

\]

This will satisfy the functional equation, but only if you can turn this heuristic into a proof. Which, I was unable to do. But I was only off by a few lemmas.

Not sure what else you can do here... Your question is very fucking hard, don't expect an honest and easy answer to it.
