A lab that explores Monstrous Moonshine through representation theory.

AboutAbout the lab
Exploring moonshine through representation theory.
The Carnahan Lab studies representation theory, with an emphasis on low-dimensional physics and number theory.
Its main problem is Monstrous Moonshine, which involves infinite-dimensional Lie algebras, vertex algebras, algebraic curves, and modular functions.
Recently, the lab has also been working on computer-based formalization in the programming language Lean 4, centered on vertex algebras and Lie algebras.
Key terms
- Monstrous Moonshine
- A mysterious correspondence linking the Monster group, a huge finite group, with modular functions. It is the main problem of this lab.
- Vertex algebra
- One of the algebraic structures involved in the study of moonshine. It has also recently become a subject of formalization in Lean 4.
- Modular function
- A function with a specific defining property under certain kinds of transformations. It is involved in the study of moonshine.
- Formalization
- Writing out mathematical definitions and proofs in a form that a computer can verify.
