Ran, Ziv The structure of Gauss-like maps. (English) Zbl 0547.14004 Compos. Math. 52, 171-177 (1984). This paper studies a notion which generalizes the classical one of Gauss map attached to an immersion into projective space or an abelian variety. It is proved that such a generalized Gauss map, if proper, always Stein- factorizes through a holomorphically locally trivial fibration with homogeneous-space fiber. Special cases: an (immersed) submanifold of general type X in an abelian variety has finite Gauss map; equivalently, the canonical bundle \(K_ X\) is ample (conjecture of Ueno); an (immersed) nonlinear submanifold of projective space has finite Gauss map (first proved by Zak). A number of variants and other special cases are also presented.
