Eisenstein class of a torus bundle and log-rigid analytic classes for ${\mathrm{SL}}_n(\mathbb{Z})$

Martí Roset, Peter Xu

Starting from a topological treatment of the Eisenstein class of a torus bundle, we define log-rigid analytic classes for ${\mathrm{SL}}_n(\mathbb{Z})$. These are group cohomology cl…
