The Cubic Representation of a Submanifold

Bang-yen Chen, Wei-Eihn Kuan

Abstract.

Let $f:M\rightarrow E^m$ be an  immersion of a 
manifold in a Euclidean space. Then the tensor product map $f^3:=f\x f\x
f:M \rightarrow E^m\x E^m\x E^m\cong E^{m^3}$ is called the cubic
representation of the submanifold. The purpose of this article
is to investigate the geometry of the cubic representation of a
spherical submanifold. Several  theorems in this respect are
obtained.
