Examples of non-Kähler Calabi-Yau manifolds with arbitrarily large
arXiv:2102.13437
Abstract
We construct non-Kähler Calabi-Yau manifolds of dimension 4 with arbitrarily large 2nd Betti numbers by smoothing normal crossing varieties. The examples have K3 fibrations over smooth projective varieties and their algebraic dimensions are of codimension 2.
