1. 片田　舞, Stable rational cohomology of the IA-automorphism groups of free groups, Tokyo--Seoul Conference in Mathematics, 2023 Topology and Geometric Group theory, 2023.10, The IA-automorphism group IAn of the free group Fn is a normal subgroup of the automorphism group of Fn, which is an analogue of the Torelli groups of surfaces. Westudy the stable rational cohomology of IAn, and its subgroup that is obtained as the image of the map induced by the abelianization map of IAn. We also consider the stable rational cohomology of the Torelli groups of surfaces..
