我们确定了自旋V4-流形的孤立奇点对其上Dirac算符指数的贡献。由这些数据，我们得到了关于球面3-流形所界定的自旋4-流形的交形以及实射影平面到4-流形的嵌入的某些约束。
We determine the contributions of isolated singularities of spin V 4-manifolds to the index of the Dirac operator over them. From these data we derive certain constraints on the intersection forms of spin 4-manifolds bounded by spherical 3-manifolds, and also on the embeddings of the real projective planes into 4-manifolds.
