He claims you can construct holomorphic tetration \(\text{tet}_b(z)\) in \(b\) everywhere except a branching problem at \(\eta\) and \(0\). His paper is very enlightening, as the majority of it is analysing how the fixed points behave within and outside the Shell-Thron region.

I was reading his paper about the double dagger method, but not this one yet. When skimming through however, I don't see any proofs for the construction (convergence and equality to Kneser). Ok, but if I understand that properly, he says that numerically his solution (which is supposed to be Kneser's) can be continued into the Shell-Thron region except \(\eta\) is a branch point.
(Or does he give a proof that Kneser can be (without any numerical assumptions) continued through the Shell-Thron boundary?)
That's cool, and actually my experiments with the regular iteration look similar.

No, I, since always, use sage (online even, on cocalc.com) for any computational needs.
