此注释是为了观察参考文献附录 B 中计算的积分 B3。 1 不是特定情况 mn 的超对称 IZ 积分,而是对应于随后对所有特征值对 IZ 积分进行积分并且考虑一些对称性属性后保留的表达式。由于某些应用不需要对特征值进行进一步积分,因此两个表达式之间的差异至关重要。
This note is to observe that the integral B3 calculated in the Appendix B of Ref. 1 is not the supersymmetric IZ integral for the particular case mn, but it rather corresponds to the expression that survives when the IZ integral is subsequently integrated over all the eigenvalues and after some symmetry properties are taken into account. Since some applications do not require a further integration over the eigenvalues, the difference between the two expressions is of basic importance.
