摘要

我们计算了自由群Fn的自同构群的上同调群，其系数在标准有理式H1（Fn，Q）及其对偶的任意张量积中，且n相对于上同调度和张量因子的数目足够大。

Stable cohomology of Aut(Fn) with bivariant twisted coefficients

We compute the cohomology groups of the automorphism group of the free group

F_{n}

, with coefficients in arbitrary tensor products of the standard rational representation

H_{1} (F_{n}, Q)

and its dual, in a range where n is sufficiently large compared to the cohomological degree and the number of tensor factors.
