On the role of the Burstin-Mayer metric for surfaces in \(\mathbb{R}^ 4\)
There exist different approaches for a theory of non-degenerate surfaces in affine \(A\)-space; the first is due to Burstin and Mayer who introduced a unimodular invariant metric. The author of this paper investigates the (non-) existence of elliptic points for this metric from a local and global viewpoint. [Reviewer's remark: An editorial survey on the different approaches will be contained in the 1995 Proceedings ``Geometry and Topology of Submanifolds VIII'', World Scientific, to appear].
