AboutAbout the lab
Exploring low-dimensional topology through Dehn surgery and 4-manifolds
The Tange Lab studies low-dimensional topology.
The lab's website lists Dehn surgery, 4-manifolds, and Heegaard Floer homology as research topics.
In addition to research, Associate Professor Tange teaches university courses, does outreach such as visits to junior high schools, high schools, and universities, and writes articles for general-audience magazines.
Key terms
- 4-manifold
- A shape that looks like ordinary 4-dimensional space when viewed on a very small scale
- Dehn surgery
- An operation that cuts out the region around a knot and glues it back in a different way to create a new 3-dimensional space
- Heegaard Floer homology
- A mathematical theory for studying the properties of 3- and 4-dimensional shapes and knots
