Contour lines of quintic polynomial $f(z) = z^5-5 z+12$ are depicted for $|z|\le 3$. The white lines show the magnitude of $f$ at $\{2, 4, 8, 16, 32, 64, 128\}$.
The black lines show the functions phase in multiples of $\pi/4$.
The paper by Lunsford was the inspiration for the cover art.
Background and Inspiration
The April 2017 cover of Mathematics Magazine.
This work was originally done for use as cover art for the April 2017 issue of Mathematics Magazine.
This is the twelfth of 25 original artworks I created for the journal Mathematics Magazine during 2015–2019.
