Hm, I think we could create an array of coefficients If we use Ansus' formula for the derivative Hence we dont need to switch between phase and function space and. We can work all the time with the coefficient array. The algorithm would then be: Take some initial guess for Then compute the continuum sum. Multiplying with add g'(0)/g(0) Then take the integral. Repeat these steps till convergent. But my fear is that it will not converge. Quote:Also, what about my question about the graph? Hey actually I never considered graph of tetration with complex bases. I would guess that it is somewhat distorted real tetration. But I think one would need contour plots, or complex color plots, to have a bigger picture.

Numerical algorithm: The problem is, what should the lower bound on the integral be? And how do you find
Graph of tetration at the complex base: So did the graph I gave surprise you? Or what?

I just finished the color graph of the complex tetration The scale runs from -10 to +10 on both axes (real = horizontal, imag = vertical). The white regions should have more detail in them, but due to overflow only limited detail is available. What do you think?

Wow.
The first thing that I see is that its not symmetric across the real axis, but that would probably be a side-effect of the base not being real. |
