WEAK GEOMETRIC STRUCTURES ON SUBMANIFOLDS OF AFFINE SPACES
(Received September 11, 2007, revised February 26, 2008)
A few affine invariant structures depending only on the second fundamental form relative to arbitrary transversal bundles on submanifolds of the standard affine spaces are introduced. A notion of “local strong convexity” is proposed for arbitrary codimensional submanifolds. In the case of $n$-dimensional submanifolds of $2n$-dimensional real affine spaces, complex structures on the ambient spaces are used as a tool for studying real affine invariants.
