The first homology of $\operatorname{IA}_n$ with coefficients in spaces of Jacobi diagrams
Abstract
The aim of this paper is to compute the first homology of $\operatorname{IA}_n$ with coefficients in the $\operatorname{Aut}(F_n)$-module $A_2(n)$ of Jacobi diagrams of degree $2$ on $n$-component oriented arcs. We also prove the self-duality of the $\operatorname{Aut}(F_3)$-submodule $A''_2(3)$ of $A_2(3)$ which is generated by a certain element.
