Abstract:
We construct some complete Spin(7)-holonomy Riemannian metrics on the noncompact orbifolds that are $\mathbb R^4$-bundles with an arbitrary 3-Sasakian spherical fiber $M$. We prove the existence of the smooth metrics for $M=S^7$ and $M=SU(3)/U(1)$ which were found earlier only numerically.
