我们将Alvarez- Gaume, Witten和Kefeng Liu的“神奇消去”公式推广到一个涉及额外复杂线束的扭曲版本。我们应用我们的结果讨论了Ochanine, Finashin和Zhang的高维Rokhlin型同余之间的内在关系。特别地,给出了Finashin同余的解析证明。
We extend the "miraculous cancellation" formulas of Alvarez- Gaume, Witten and Kefeng Liu to a twisted version where an extra complex line bundle is involved. We apply our result to discuss intrinsic relations between the higher dimensional Rokhlin type congruences due to Ochanine, Finashin and Zhang. In particular, an analytic proof of the Finashin congruence is given.
