= Vogan diagram
{wiki=Vogan_diagram}
A Vogan diagram is a tool used in the study of representation theory, particularly in the context of Lie algebras and algebraic groups. It serves as a visual representation that helps to understand the structure of representations of these mathematical objects. In essence, a Vogan diagram is a graphical representation that captures information about the weights of representations, the roots of the associated root systems, and their relationships.
