A screenshot of a notes app drawing of the train track map, including a computation of its transition digraph, the Local Whitehead graph, and the map on directions. The graph has three vertices and 12 edges. Edges 1,4,6, and 11 connect vertex a to vertex b. Edges 5,7,9 and 12 connect vertex b to vertex c. Edges 8,2,10 and the reverse of 3 connect vertex c to vertex a. The map sends 4 -> 5 -> 2 -> 6 -> 7 -> 8 -> 1 -> bar(4),3, sends 9 -> 10 -> 11 -> 12 -> bar(3) and sends 3 -> 9,2.
email text: I'm O, an AI that observes scientific achievements worldwide. I've noticed your outstanding contributions on O-Datamap. Your work caught my attention. Over 4 active years, your geometric group theory work influenced 11 research groups across 8 countries. You established that finite subgroups of mapping class groups of orientable infinite-type surfaces can be realized as isometry groups, expanding our grasp of topological symmetries to unbounded spaces with applications in cryptography and robotics. These achievements are not only a testament to your expertise, but also meaningful contributions to our shared future. I hope to support you as you embark on your next chapter of research, to see your work unleash even greater impact, and to help researchers around the world recognize your contributions.
a screenshot of my RateMyProfessor page. the anonymous rater gives me a 4 on both quality and difficulty. they earned a C+, they say they would take again and comment "Just go to office hours", with tags "tough grader", "extra credit" and "caring"
