First I noticed that at base 2 humps would appear at around 0.5 and 1.5, and if we increased the base, the humps would get sharper and sharper and taller and taller. So I figured, there must be a base value where the humps disappear altogether. My first guess was eta, since everyone talks about how closely related it is to tetration, but when I made a graph of there were still visible humps at 0.5 and 1.5. Disappointed, and intrigued by the cheta function, I tried using the upper superfunction of eta, and voila, the values converged miraculously.

So it was more just a shot in the dark as opposed to a real mathematical deduction as to why we used base eta.

fatb(2,-1,2) = 2º2=4 -> 2+2=4

fatb(3,-1,3) = 3º3=5 -> 3+2=5

fatb(4,-1,3) = 4º3=5 - it's correct. because that's here down:

aºb

if a>b then a+1

if b>a then b+1

if a=b then a+2 or b+2

no, this isn't zeration, this a different operator designed to preserve the ring structure of operators [t-1] and [t].

I anyway wonder whether thats possible at all.

As is not even differentiable at 1, I wonder whether f is. Did you compare the derivations from left and right?

No I haven't compared the derivations, I'll do that though. It's hard for me to think up tests I can do with only highschool math under my belt

hmm, I really understand where you're coming from with using a standard notation instead of the triangles, it saves a lot of confusion, but I think that for the same reason the gamma function is written instead of , logarithmic semi-operators should be written using their own notation--just to be clear this is only one extension of hyper operators. I know that simply stating this is the natural extension of hyper operators will step on a lot of people's toes.

Also, I have something very interesting to report!

My conjecture can be proved for .

and if anyone knows their deltation, like I just explained

therefore:

The proof can actually be made even simpler,

consider, :

therefore since:

,

, and since there's a fixpoint at e,

This proves a beautiful connection between logarithmic semi operators and the cheta function.

And also gives me a new beautiful identity:
