AboutAbout the lab
Exploring the world of numbers through Galois representations
Taguchi Lab studies number theory.
In its papers to date, the lab has dealt with Galois representations and with the moduli spaces that classify them.
The lab's website also offers explanations of topics such as Fermat's Last Theorem, class field theory, and p-adic numbers.
Key terms
- Number theory
- A field of mathematics that studies the properties of integers and prime numbers. Also called higher arithmetic.
- Galois representation
- A way of writing the ways the roots of an equation can be permuted (the Galois group) in the form of matrices.
- p-adic number
- A number system that measures how close numbers are to each other by looking at how many times they are divisible by a prime p.
ResearchResearch themes
*Illustrative imageGroups of Rational Points on Elliptic Curves and Related Objects
The rational points on elliptic curves and similar objects form a group, and the structure of this group is a major theme in number theory. The lab determines what this group (the Mordell-Weil group) looks like when considered over very large number fields.
