چکیده
is biholomorphic equivalent to the Satake compactification of H2/Γ′ for a certain subgroup Γ′ ⊂ Sp(2, Z). This variety has 96 singularities which correspond to certain zero-dimensional cusps and these singularities are ordinary double points (nodes). In the paper [CM] it has been pointed out that the results of [GN] imply that a (projective) small resolution of this variety is a rigid Calabi-Yau manifold X̃ . We describe the basic occurring groups: We use the standard notations, M = ( A B C D ) :

Some Siegel threefolds with a Calabi-Yau model
2009 Introduction In the following we describe some examples of Calabi-Yau manifolds that arise as desingularizations of certain Siegel threefolds. Here by a Calabi-Yau mani-fold we understand a smooth complex projective variety which admits a holo-morphic differential form of degree three without zeros and such that the first Betti number is zero. This differential form is unique up to a const...
متن کاملOn Siegel threefolds with a projective Calabi–Yau model
In the papers [FS1], [FS2] we described some Siegel modular threefolds which admit a weak Calabi–Yau model.*) Not all of them admit a projective model. In fact, Bert van Geemen, in a private communication, pointed out a significative example which cannot admit a projective model. His comment was a starting motivation for this paper. We mention that a weak Calabi–Yau threefold is projective if, ...
متن کاملPrimitive Contractions of Calabi - Yau Threefolds
We construct examples of primitive contractions of Calabi–Yau threefolds with exceptional locus being P 1 ×P 1 , P 2 , and smooth del Pezzo surfaces of degrees ≤ 5. We describe the images of these primitive contractions and find their smoothing families. In particular we give a method to compute the Hodge numbers of a generic fiber of the smoothing familly of each Calabi–Yau threefold with one ...
متن کاملPrimitive Calabi-yau Threefolds
A Calabi-Yau threefold is a complex projective threefold X (possibly with some suitable class of singularities, say terminal or canonical) with ω X ∼ = O X and h 1 (O X) = h 2 (O X) = 0. One of the fundamental gaps in the classification of algebraic threefolds is the lack of understanding of Calabi-Yau threefolds. Here I will try to set forth a program to bring the morass of thousands of exampl...
متن کاملInstanton Sums and Monodromy
String theorists are interested in several quantum field theories and string theories associated with Calabi–Yau threefolds. The most straightforward of these to formulate is the two-dimensional quantum field theory which governs the physics of a string propagating on the Calabi–Yau threefold. However, making calculations directly with that quantum field theory is quite difficult. To the extent...
