Abstract: Given a hypersurface X = V ( f ) in a complex projective space, the Gauss map of X can be regarded as the restriction of the gradient map of f on X. We say, the hypersurface X has degenerate Gauss map if general fibers of the Gauss map have positive dimension. Especially for cubic hypersurfaces with degenerate Gauss map, there is an interesting classification of them. We will study several types of cubic hypersurfaces and the relation between them.
