Suppose $G$ is a split connected‎ ‎reductive orthogonal or symplectic group over an infinite field‎
‎$F,$ $P=MN$ is a maximal parabolic subgroup of $G,$ $frak{n}$ is‎
‎the Lie algebra of the unipotent radical $N.$ Under the adjoint‎
‎action of its stabilizer in $M,$ every maximal prehomogeneous‎
‎subspaces of $frak{n}$ is determined‎.
