چکیده
We show that the natural S-bundle over a projective special Kähler manifold carries the geometry of a proper affine hypersphere endowed with a Sasakian structure. The construction generalizes the geometry of the Hopf-fibration S −→ CPn in the context of projective special Kähler manifolds. As an application we have that a natural circle bundle over the Kuranishi moduli space of a Calabi-Yau threefold is a Lorentzian proper affine hypersphere.

Seifert Gm-bundles
Seifert fibered 3–manifolds were introduced and studied in [Sei32]. (See [ST80] for an English translation.) Roughly speaking, these are 3–manifolds M which admit a differentiable map f : M → F to a surface F such that every fiber is a circle. Higher dimensional Seifert fibered manifolds were investigated in [OW75]. The authors observed that in many cases of interest Seifert fibered manifolds c...
متن کاملSpecial Kähler manifolds: a survey
This is a survey of recent contributions to the area of special Kähler geometry. It is based on lectures given at the 21st Winter School on Geometry and Physics held in Srni in January 2001. 1 Remarkable features of special Kähler manifolds A (pseudo-) Kähler manifold (M,J, g) is a differentiable manifold endowed with a complex structure J and a (pseudo-) Riemannian metric g such that (i) J is ...
متن کاملRealisation of special Kähler manifolds as parabolic spheres
We prove that any simply connected special Kähler manifold admits a canonical immersion as a parabolic affine hypersphere. As an application, we associate a parabolic affine hypersphere to any nondegenerate holomorphic function. Also we show that a classical result of Calabi and Pogorelov on parabolic spheres implies Lu’s theorem on complete special Kähler manifolds with a positive definite met...
متن کاملA Special Class of Hyper-kähler Manifolds
We consider hyper-Kähler manifolds of complex dimension 4 which are fibrations. It is known that the fibers are abelian varieties and the base is P. We assume that the general fiber is isomorphic to a product of two elliptic curves. We prove that such a hyper-Kähler manifold is deformation equivalent to a Hilbert scheme of two points on a K3 surface. 1. Preliminaries First we define our main ob...
متن کاملHolomorphic isometry from a Kähler manifold into a product of complex projective manifolds
We study the global property of local holomorphic isometric mappings from a class of Kähler manifolds into a product of projective algebraic manifolds with induced FubiniStudy metrics, where isometric factors are allowed to be negative.
