The lab specializes in number theory, exploring elliptic curves and special values of L-functions.

AboutAbout the lab
Elliptic curves through the lens of number theory.
Kezuka Lab specializes in number theory and studies elliptic curves and Iwasawa theory.
The lab also studies special values of L-functions and the Birch and Swinnerton-Dyer conjecture.
Key terms
- Elliptic curve
- A curve defined by a cubic equation such as y² = x³ + ax + b. Its points can be added to one another.
- Iwasawa theory
- A theory that considers an infinite tower of number fields stacked one on top of another, and studies arithmetic quantities across the tower as a whole.
- Birch and Swinnerton-Dyer conjecture
- An unsolved conjecture stating that the number of rational points on an elliptic curve is determined by the behavior of its L-function.
