Hints and tips:
  • You may need to look up some unfamiliar terms in the title or description to get more of a sense of what is involved.
  • If the project has "No" in the "Current Availability:" field, it is already taken or not being offered this academic year but may be available again in future years.
  • The supervisor name links to a contact details webpage so, if you are interested, you can arrange to discuss this project or even propose a related topic of your own.

Title: Curve shortening flow in the plane
Supervisor:

Dr Reto Buzano
Research Area: Geometry and Analysis
Description:

This project focuses on a different curve shortening process, namely the curve shortening flow, a "geometric heat equation" which deforms a closed curve (in the plane) in such a way that it becomes more and more round (while at the same time shrinking it towards a point). The goal of this project is to study some properties of this flow and reprove the result that any closed curve without self-intersections becomes eventually convex before vanishing to a (round) point. This project is quite a bit harder than the project on Birkhoff's process described above, it is therefore only recommended for particularly strong students. You will have to read actual research papers, follow and understand the computations and restate the results in your own words.
Further Reading:

Literature suggestions will be provided depending on the level of the student and the precise expected outcome (which can be discussed before the start of the project).

Other Information:

A rather solid background in Analysis is required – you will have to understand and possibly reformulate lengthy abstract computations!
