摘要：

In this paper, we study n-dimensional improper affine spheres of which the center map is congruent to the original immersion. We show how to construct such hypersurfaces starting from (n - 1)-dimensional proper elliptic affine hyperspheres. We also show that they correspond to solutions of the Monge-Ampere equations which are homogeneous of degree 2.
