What it is
A graphical notation encoding root systems, used to classify semisimple Lie algebras and finite reflection/Weyl groups, introduced by Eugene Dynkin.
What it led to
- complete classification of simple Lie algebras
- classification of Weyl and reflection groups
- standard tool in representation theory and theoretical physics
- use in classifying singularities and in string theory
