Ideally, your mathematics comps project should be driven by your interests and aspirations. It should be aesthetically beautiful and practically useful. It should be challenging but not impossible. It should make use of multiple undergraduate math courses, and should demonstrate your ability to work in a group. Unfortunately, inventing a project to fulfill all of these objectives is not easy.
My current research concerns certain mathematical modeling problems in geology. Despite my background in "pure" mathematics, I find that these "applied" mathematics problems satisfy my aesthetic sensibilities quite well. And they certainly require a variety of tools. For example, Lie groups and the Poincaré-Hopf theorem have both shown up in my recent work. Simply put: There's a lot of cool math out there, and much of it is useful in the sciences.
I propose that we investigate a particular mathematical problem that has arisen in my research, following this plan:
That plan sounds somewhat like an introductory PDE course with a computational bent. Depending on the students' interests, we could veer off in other directions, such as:
We could veer off in still other directions: measure theory and probability theory on homogeneous spaces, non-parametric statistics, non-linear optimization, PDEs, fluid dynamics, implementation of FEMs, etc. I have many more problems, than I have time to solve them.
The comprehensive exercise is the capstone of your Carleton education. It is your chance to demonstrate that you can pursue a sustained, difficult, open-ended project. The stated expectations of the Mathematics Department are imprecise. Let's be a little clearer:
It should go without saying that a student who is interested in distinction will try to exceed these basic expectations.
Over the summer, the motivated student might want to brush up on multivariable calculus. As far as I know, the divergence theorem is often not taught in Carleton's ten-week multivariable calculus course. So students could read up on partial derivatives, gradients, curl, divergence, surface integrals, and the divergence theorem. A really motivated student might then go on to study the derivation of Navier-Stokes.
