Their first approximation where denoted by $\sigma=-1.84140566...$ and $pent_e (-\infty)=sln(\sigma)={{}^\sigma}e=\sigma...$ (where pent is computed using their approximation). .. [1] Rubtsov, Romerio - Notes on Hyper-Operations, Progress Report -NKS forum III, Final review 3, 2006. http://math.eretrandre.org/tetrationforu...hp?aid=222 Thank you for the link, I add it to the article http://mizugadro.mydns.jp/t/index.php/Superfunction Do you understand, how do they calculate the tetration? I think, my algorithms are more efficient, because Rubtsov and Romerio do not present any complex map of tetration, nor pentation. Quote: The way you plot function is really nice, is the same way one draws geographical map using contour lines! Is a common method to plot complex functions? http://mizugadro.mydns.jp/t/index.php/Complex_map Some complex maps are presented in the handbook of mathematical functions, see, for example, figure 7.3 at http://people.math.sfu.ca/~cbm/aands/abr...stegun.pdf This refers to the past century. In this sense, already common. « Next Oldest | Next Newest »
