给出了BSL(2,C δ)上秩为2的重言平坦复向量丛的全Cheeger-Chem-Simons类的一个公式.这改进了Dupont和Zickert [6]的公式,其中类仅计算模2-挠。
We present a formula for the full Cheeger-Chem-Simons class of the tautological flat complex vector bundle of rank 2 over BSL(2, C δ ). This improves the formula by Dupont and Zickert [6], where the class is only computed modulo 2-torsion.
