Homma Lab
Machine-translated · View original
A lab that explores the essence of geometry and physics through Dirac operators.

AboutAbout the lab
Exploring geometry through Dirac operators.
The Homma Lab studies spin geometry from the perspectives of differential geometry and global analysis.
The lab studies the Dirac operator, a differential operator, from various angles, including differential geometry, global analysis, and representation theory.
Specifically, it works on topics such as spin geometry, gauge theory, twistor theory, and index theorems.
Another aim of the lab is to understand the geometric and analytic properties of differential operators determined by geometric structures on Riemannian manifolds.
Key terms
- Spin geometry
- A branch of geometry that studies shapes using special quantities called spinors
