The lab studies representations of quantum loop algebras and infinite-dimensional Lie algebras.

AboutAbout the lab
Studying how algebras act, through representations.
Prof. Kodera researches representation theory.
Representation theory is a field that studies how algebras act by translating them into concrete forms such as matrices.
The objects of study are representations of quantum loop algebras, Yangians, and related infinite-dimensional Lie algebras.
Crystal bases and quiver varieties are also listed as research areas.
Key terms
- Representation theory
- A field that studies how algebras act by translating them into matrices or transformations of vector spaces.
- Yangian
- A type of quantum group: an infinite-dimensional algebra that arose from the study of integrable systems.
- Quiver variety
- A space built from a diagram of points and arrows (a quiver). It allows representations of algebras to be captured in geometric form.
ResearchResearch themes
The specialty is representation theory.
