Centroaffinely Homogeneous Surfaces in \RRR
Huili Liu, Changping Wang
Abstract.
A nondegenerate centroaffine surface in $\R^3$ is called homogeneous, if for
any two points $p$ and $q$ on the surface there exists a centroaffine
transformation in $\R^3$ which takes the surface to itself and takes $p$ to $q$.
In this paper all centroaffinely
homogeneous surfaces in $\R^3$ are determined
up to centroaffine transformations.
