Tsuji Lab
Machine-translated · View original
An arithmetic geometry lab that studies geometric objects through the world of p-adic numbers.

AboutAbout the lab
Seeing geometry through p-adic eyes.
The Tsuji Lab studies p-adic Hodge theory and p-adic cohomology in the field of arithmetic geometry.
The lab investigates the p-adic cohomology of algebraic varieties defined over p-adic fields.
It also studies special values of L-functions and their applications to p-adic L-functions.
Key terms
- p-adic field
- A number system built on the idea of measuring how close numbers are by how many times they are divisible by a prime p
- Cohomology
- A tool for extracting information about a shape, such as its holes and how its parts are connected, in the language of algebra
- L-function
- A function that packages the properties of numbers into the form of an infinite series. The Riemann zeta function is the best-known example
ResearchResearch themes
The lab's research field is arithmetic geometry, with p-adic Hodge theory and p-adic cohomology as its themes. It studies algebraic varieties over p-adic fields and also works on applications to L-functions.
