A Family of Compact Complex-Symplectic Calabi-Yau Manifolds that are Nonkähler

Abstract

We construct a family of $6$-dimensional compact manifolds $M(A)$, which are simultaneously diffeomorphic to complex Calabi-Yau manifolds and symplectic Calabi-Yau manifolds. They have fundamental groups $\mathbb{Z}\oplus \mathbb{Z}$, their odd-dimensional Betti numbers are even, they satisfy the hard Lefschetz property, and their real homotopy types are formal. However, $M(A)\times Y$ are not homotopy equivalent to any compact Kähler manifold for any topological space $Y$.
