   algebras Definition: For an exceptional complex simple Lie algebra $\mathfrak g$ CITE{WikiExceptional},-  let $V_{\mathfrak g}(\lambda)$ be the irreducible representation of $\mathfrak g$-  with highest weight $\lambda$; when $\mathfrak g$ is fixed, $V(\lambda)$ means $V_{\mathfrak-  g}(\lambda)$.
