Sneak peek into the International Congress of Mathematicians (ICM): There will be a #MathArt gallery, which is already #openAccess at www.imaginary.org/gallery/icm-.... It does feature my work "Heart of Domain Coloring" (with H. Lipschütz and U. Reitebuch). Go and give it a look!

Domain coloring allows for the visualization of complex functions with color-lookups via a pre-image. The white grid lines correspond to function values with integer real or imaginary part. All other complex numbers are mapped to different colors by their angle to the positive real axis, using four color spectra, one for each quadrant. By placing zeros and poles in a highly symmetric configuration, we deform the coordinate axes shown in black into heart shapes. The image was created digitally by a pixel-wise evaluation of the input function.
