 Spiral Numbers Gottfried Ultimate Fellow Posts: 763 Threads: 118 Joined: Aug 2007 03/01/2016, 12:30 PM (This post was last modified: 03/01/2016, 03:33 PM by Gottfried.) "Log-polar" (see also wikipedia https://en.wikipedia.org/wiki/Log-polar_coordinates ) representation might fill the prerequisites a tiny bit better. For instance the regular tetration with a complex fixpoint, curving around the fixpoint can then be approximated by linear interpolation and that interpolation agrees better and better with the regular tetration if the coordinate is translated into vicinity of the fixpoint using the functional equation. I have a picture of this in my comparision "5 methods for interpolation" ( http://go.helms-net.de/math/tetdocs/Comp...ations.pdf ) posted here earlier.
