The SMALL REU
I advised groups as part of Williams College’s SMALL REU in 2017, 2018, 2020, and 2021. Check out the research page for our publications!
I have advised eight senior honors theses at Williams College, as well as a minithesis:
- Madeleine Elyze ’18: On higher distance commuting matrices
- Andrew Scharf ’18: Intersections of tropical surfaces
- Jian Lu ’19: Time complexities in max-linear systems
- Max Everett ’21: Multiplicity-free gonality on graphs
- Robin Hung ’21: The tropical Three Conics Theorem
- Ben Weber ’21: On gonality-related graph parameters
- Jason Meintjes ’22: Tropical Brianchon’s Theorem
- Lucas Tolley ’22: Higher order gonalities of graphs
- Robin Eagleton ‘22.5: Characterizing graphs of small scramble number (minithesis)
Most of my upper level classes include a final project. Here are a few of those!
Nullstellenfont (by Ben Logsdon ’20 and Anya Michaelsen ’19, for Math 487: Computational Algebraic Geometry in Spring 2019)
Algebraic geometry studies varieties, which are shapes defined by polynomial equations. For instance, polynomials in two variables define curves in the plane. For their final project, Ben and Anya designed a typographical font called “Nullstellensatz”, which lets you represent any string of letters using a single polynomial equation! For instance, here’s a polynomial defining a curve that looks like my name. If you’d like to make your own, you can download their code here.
Chip-firing tool (by Markus Feng ’21 for Math 334: Graph Theory in Spring 2019)
Chip-firing games on graphs involve placing an integer number of chips on the vertices of the graph, and then moving those chips around by “firing” vertices, which makes them donate a chip to each neighbor. For his final project in my Graph Theory class, Markus designed a great tool for drawing graphs and then performing chip-firing moves on them.
This one isn’t really a final project, but the students in Math 474: Tropical Geometry put together a gallery of tropical curves. Check it out here!
