AboutAbout the lab
Ramification Theory and Invariants
The Yatagawa Lab studies ramification theory and invariants in arithmetic geometry.
Among other topics, it investigates the relationship between invariants that appear in algebraic geometry and invariants of “ramification” that appear in algebraic number theory.
Key terms
- Arithmetic geometry
- A field that uses the methods of algebraic geometry, which studies geometric figures through equations, to investigate properties of integers and of solutions to equations
- Algebraic number theory
- A branch of mathematics that studies properties of numbers using “algebraic integers,” which extend the notion of integers
- Ramification
- A phenomenon in which, when a number system is extended, a prime splits into a product in which the same factor is repeated. It corresponds to branching in geometric figures
- Invariant
- A quantity that does not change when an object is transformed or viewed in a different way. It serves as a clue for telling objects apart
