Calabi-Yau threefolds of quasi-product type.
Cohomologie quantique
Computing the level of a modular rigid Calabi-Yau threefold.
Construction of Calabi-Yau 3-folds in .
Cyclic coverings of Fano threefolds
We describe a series of Calabi-Yau manifolds which are cyclic coverings of a Fano 3-fold branched along a smooth divisor. For all the examples we compute the Euler characteristic and the Hodge numbers. All examples have small Picard number .
