对于一类称为弱双曲的自对应C,我们给出了C的不动点分量对C的Lefschetz数的贡献的计算公式。该公式适用于上同调的莱夫谢茨数,其系数在层的可构造复形中(例如相交同调)。
SummaryFor a class of self-correspondencesC calledweakly hyperbolic, we give a computable formula for the contribution of a fixed point component to the Lefschetz number ofC. The formula applies to Lefschetz numbers of cohomology with coefficients in a constructible complex of sheaves (such as intersection homology).
