Classification of coadjoint orbits for the maximal unipotent subgroup in the simple group of type F_4

Matvey A. Surkov

Let N be the maximal unipotent subgroup in the simple algebraic group of type Φ. It naturally acts on the space dual to the Lie algebra n of N, and this action is called coadjoint.…

Rook placements in $G_{2}$ and $F_{4}$ and associated coadjoint orbits

Mikhail V. Ignatev, Matvey A. Surkov

Let $n$ be a maximal nilpotent subalgebra of a simple complex Lie algebra with root system $Φ$ . A subset $D$ of the set $Φ^{+}$ of positive roots is called a rook placemen…
