Equivalence classes of Borel-stable subspaces

An equivalence relation is defined on the set of subspaces of the nilradical which are stable under the Borel subgroup. A partial order is defined and studied on the equivalence classes of this relation, and connections are made to a partial order defined by Achar on a related set.
