regular tetration base sqrt(2) : an interesting(?) constant 2.76432104
#7
Hi Sheldon -

thanks for the hint to the tanh-function. I'll give it a try!

I think we need only the appropriate imaginary iteration height to compute the respectively duals. Levenstein- numbers? ;-)
What is the definition/equation for a Kneser solution dual? The Kneser solution is not periodic. Would the dual of -infinity, which is sexp(-2) be sexp(2)?

No, the "dual" is just the iterate with an appropriate (purely) imaginary height (which -in the case we work using such a function - changes the sign of the schröder-function-value), where the result is again real. if would denote the Kneser-method iteration from x using height h, then in our case with base = sqrt(2), it should be . It's similar to take the purely imaginary with a multiple of pi as exponent of the exponential-function to arrive at the negative part of the number line .

And the result should be real and near the "dual" taken by the regular iteration.
