A compact manifold with holonomy Spin(7) from Beauville's Calabi-Yau fourfold
arXiv:1408.2205
Abstract
We give a new example of a compact manifold with holonomy Spin(7) from a Beauville's Calabi-Yau fourfold. Its construction is very concrete, starting with products of elliptic curves with complex multiplications --- so probably more accessible to physicists.
