Continuum sum - a new hope

Hey Kobi,

thanks for sharing your ideas.

The formula looks very interesting, however it seems only useful with the natural continuum product which you describe, which limits the base range to . It seems indeed to yield regular iteration tetration, a nice finding.

For the case we however lack an expression of continuous in (and if we had that then we would already have tetration). So we have no possibility to compute the continuum product in an alternate way, which however would be necessary for the case .

Actually I also have no experiences with partial differential equations. So we have to wait until someone comes with more knowledge about it and can make use of this equation.

I think we can continue in a similar fashion and find values in higher derivatives order, but I am not sure.

I think this is easier derived via the standard methods of regular iteration at the fixed point.

Ansus, Taylor series are not the only allowed tools in computation of tetration! (Eg. would you object Dmitrii's Cauchy-integral computation only because it doesnt contain Taylor series?)
