 Is bugs or features for fatou.gp super-logarithm? Ember Edison Junior Fellow Posts: 35 Threads: 5 Joined: May 2019 07/10/2019, 12:46 PM I have been a big pressure test for fatou.gp in one month. In the post(https://math.eretrandre.org/tetrationfor...p?pid=8952) I say $Arg(base)\in({\frac{14\pi}{30}},{\frac{21\pi}{30}})\wedge({\frac{42\pi}{30}},{\frac{47\pi}{30}}),\left| base \right|<1.76.$is ill-region for fatou.gp. In fact, the ill-region for slog is little bigger the sexp. But, There's look like other problem out of the ill-region.This gif is slog for base = Pi*(-1)^(x/30), 0<=x<=59. You can see the program be pathological close to branch cut. This plot is slog for Sheldon base. It look like well-behaved.     This plot is slog for base = eta. It look like well-behaved too. base = -eta. It look like pathological.     base = sqrt(2). It look like well-behaved. base = -sqrt(2).      base = (-1)^(1/100). It's the closest base to 1. Is look like well-behaved? No, the program crash when Im(z)>$\frac{21\pi}{8}$     base = 0.8.  base = -0.105. It's the closest base to 0. « Next Oldest | Next Newest »
