About
This is an undergraduate student seminar on geometry and topology. Here is a course description for you to get an idea of how it runs and particularly for those of you who wish to register for credit.
Our theme for Fall 2025 is geometric models and their additive engineering, such as this and this. We have 3D printers handy in Research Building 3 thanks to support by the Department of Mathematics and the National Center for Applied Mathematics Shenzhen. Here are some additional suggestions and references in case you don't have a favorite example in mind yet!
We meet on Thursday/Friday in alternating weeks 4:30–5:30 pm (see schedule below) in College of Science M5024.
