The lab studies high-dimensional algebraic varieties through algebraic geometry.

AboutAbout the lab
Exploring the structure of high-dimensional varieties
The Nagai Lab studies algebraic geometry, in particular high-dimensional algebraic varieties.
The lab focuses on compact holomorphic symplectic Kähler manifolds and the algebro-geometric structures defined on them.
As related tools, it also studies moduli of semistable sheaves, geometric invariant theory, toric geometry, and higher-dimensional birational geometry.
Key terms
- Algebraic variety
- A basic geometric object in algebraic geometry, defined as the set of solutions to equations
- Symplectic Kähler manifold
- A geometric object that simultaneously has a special structure using complex numbers (a Kähler structure) and a structure for measuring area and volume (a symplectic form)
- Birational geometry
- A field of geometry that studies geometric objects by asking whether they can be regarded as the same over most of their parts
