  We study the structure of hypersurface orbital varieties of sl(N,C) (those
that are hypersurfaces in the nilradical of some parabolic subalgebra) and how
information about this structure is encoded in the standard Young tableau
associated to it by the Robinson-Schensted algorithm. We present a conjecture
for the exact form of the unique non-linear defining equations of hypersurface
orbital varieties and proofs of the conjecture in certain cases.
