Relative Chern character number and super-connection

Dexie Lin

摘要:

对于两个允许同态的复向量丛,其奇点位于奇数维球面的不交并上,给出了计算这两个复向量丛的相对陈示性数的公式.特别地,对于具有球面丛结构的自旋流形,我们给出了一个特殊扭Dirac算子的指数公式。

英文摘要:

For two complex vector bundles admitting a homomorphism, whose singularity locates in the disjoint union of some odd--dimensional spheres, we give a formula to compute the relative Chern characteristic number of these two complex vector bundles. In particular, for a spin manifold admitting some sphere bundle structure, we give a formula to express the index of a special twisted Dirac operator.
