All Complete Intersection Calabi-Yau Four-Folds


The basic classification of complete intersection Calabi-Yau four-folds, together with a computation of Euler numbers has been carried out in arXiv:1303.1832. The corresponding data, which consists of the configuration matrices and the Euler numbers, is contained in the following files:


Topological Invariants and Fibration Structure of Complete Intersection Calabi-Yau Four-Folds

In arXiv:1405.2073, the structure of complete intersection Calabi-Yau four-folds has been analyzed in more detail. In particular, all Hodge numbers, Chern classes and elliptic fibrations have been computed. The corresponding data whose format is explained in arXiv:1405.2073 is contained in the following files:
  • Four-fold list as a compressed plain text file, containing a list in Mathematica format (12.3MB compressed, 342.9MB uncompressed).
     
  • Elliptic fibrations of four-folds, as a compressed directory containing text files with lists in Mathematica format (128.4MB compressed, 4.93GB uncompressed).
