We consider the affine transformation of a nilpotent Lie group on ℝ n . Lipsman (1995) conjectured that such an action is proper in the sense of Palais if and only if the action is compact isotropy (CI) in the sense of Kobayashi. This paper gives an affirmative solution to Lipsman's conjecture in the four-dimensional case.
