On dual-projectively flat affine connections
The author introduces notions of dual-geodesic curves, dual-projective equivalence and dual-projective flatness for affine connections compatible or semi-compatible with a pseudo-Riemannian metric tensor field. He studies basic properties of these notions and gives some applications to the theory of affine hypersurfaces.
