AboutAbout the lab
Viewing figures and equations as points of a higher-dimensional figure
The Yamakawa Lab studies symplectic geometry and algebraic geometry.
In modern mathematics, mathematical objects such as figures, equations, and functions are sometimes regarded as points in a higher-dimensional figure (a moduli space).
This makes it possible to treat a deformation of the object under consideration as the movement of a point in the moduli space.
The lab particularly studies isomonodromic deformations of meromorphic connections on compact Riemann surfaces, using the complex symplectic structure of the moduli space.
Key terms
- Moduli space
- A higher-dimensional figure that collects mathematical objects such as figures, equations, and functions as points. A deformation of an object becomes the movement of a point
ResearchResearch themes
The lab studies mathematical objects such as figures, equations, and functions by regarding them as points of a moduli space, which is a higher-dimensional figure. Its research fields are symplectic geometry and algebraic geometry, and its research themes are moduli spaces of meromorphic connections, wild character varieties, and isomonodromic deformations.
