Affine Differential Geometry Definition
noun
A type of differential geometry in which the differential invariants studied are invariant under volume-preserving affine transformations.
The basic difference between Riemannian and affine differential geometry is that in the affine case we introduce volume forms over a manifold instead of metrics.

Origin of Affine Differential Geometry
-
The term reflects the categorisation developed by German mathematician Felix Klein for his Erlangen programme (1872, Vergleichende Betrachtungen über neuere geometrische Forschungen), in which he found a useful distinction between projective , affine and Euclidean geometry (in order of increasing restrictiveness). (Riemannian geometry was not initially included.)
