The homology of $Out (F_{8})$ and $Aut (F_{7})$

Maroš Grego, Tomáš Vítek, Thomas Willwacher

We compute the rational homology of $Out (F_{8})$ and $Aut (F_{7})$ , and several related groups. We also show that the Eisenstein classes in $H_{7} (Aut (F_{5}))$ an…

Triple delooping for multiplicative hyperoperads

Florian De Leger, Maroš Grego

Using techniques developed by Batanin and the first author, we extend the Turchin/Dwyer-Hess double delooping result to further iterations of the Baez-Dolan plus construction. For…
