The lab studies algebraic geometry over number fields.

AboutAbout the lab
Studying geometric shapes over the world of numbers.
The Kawaguchi Lab studies algebraic geometry over number fields.
In joint research, the lab works on tropicalization, which maps a geometric shape to a piecewise-linear shape in order to study it, and on the theory of heights, which measures the complexity of numbers.
The lab has also co-authored a book presenting the complete proof of the Mordell conjecture via Diophantine geometry.
Key terms
- Number field
- A set of numbers formed by adjoining solutions of a certain equation to the rational numbers
- Tropicalization
- A method of studying algebraic shapes by mapping them to shapes made of line segments or polyhedra
- Height
- A quantity that measures how complex the numbers describing a point, such as a rational number, are
ResearchResearch themes
The lab studies algebraic geometry over number fields, using tropical geometry and the theory of heights to investigate the properties of algebraic varieties.
