The type C induction conjecture for Borel orbit closures

Consider symmetric representation varieties of the Seesaw algebra in type $C$, and Borel orbit closures in these varieties. The phrase “induced by type $A$” refers to the induction relation between orbit closures in the symmetric setting and the corresponding type $A$ setting.

Type C induction conjecture. In type $C$, Borel orbit closures are induced by type $A$.

This is stated in the discussion of the conjectural behavior by type. The surrounding text notes that the type $C$ symmetric representation varieties are irreducible, whereas the authors are not currently sure about type $B$; in type $D$ there are two dense orbits.
