I also remember someone asking about fixedpoints of tetration, so I graphed some complex plots of \( e^z - z \) and \( {}^{z}e - z \) for comparison.
It looks as though there are fixedpoints of tetration at:
It looks as though there are fixedpoints of tetration at:
- \( z = -1.85 \)
- \( z = 0.8 \pm 1.5 i \)
- \( z = 3 \pm 0.5 i \)
- and more...
