B-orbits in abelian nilradicals of types B, C and D: towards a conjecture of Panyushev

Nurit Barnea, Anna Melnikov

Let $B$ be a Borel subgroup of a semisimple algebraic group $G$ and let $m$ be an abelian nilradical in $b = Lie (B)$ . Using subsets of strongly orthogonal…

B-orbits of square zero in nilradical of the symplectic algebra

Nurit Barnea, Anna Melnikov

Let $S P_{n} (C)$ be the symplectic group and $sp_{n} (C)$ its Lie algebra. Let $B$ be a Borel subgroup of $S P_{n} (C)$ , $b = Lie (B)$ an…
