Abstract

In this paper, we study the multiple Riemannian products \({\mathbb {R}}^q\times \prod _{i=1}^{r}M_i^{n_i}(c_i)\), immersed in the affine space as locally strongly convex affine hypersurfaces with semi-parallel cubic form relative to the Levi-Civita connection of affine metric, where each \(M_i^{n_i}(c_i)\) is a space form of nonzero curvature \(c_i\). As the main result, we establish the classification of such hypersurfaces if either \(q\le r\) or the immersions being affine hyperspheres.
