I am mentioned in these articles:
Designed by Sheila Hall of Media Profunda in collaboration with me.
In 2004, as part of Project 25: 25 art projects in 1 year, Sheila designed this logo for the topic of my thesis.
The shine streaks are the parentheses!
The design depicts the classification of subgroups of the isometry group of a delta-hyperbolic space. The blue curves represent orbits, green represent fixed points, and pink represent the end-points of loxodromics. The dotted lines represent a potential boundary. This cartoon should be read as one would the disk-model for the hyperbolic plane.
The sticker was printed in 2025 to publicize my joint work with Sahana Balasubramanya.
