摘要
We discuss the higher-dimensional generalization of gravitational instantons by using volume-preserving vector fields. We give special attention to the case of eight dimensions and present a new construction of the Ricci-flat metric with holonomy in Spin(7). An example of the metric is explicitly given. Furthermore, it is shown that our formulation has a natural interpretation in the Chern-Simons theory written by the language of superconnections.
