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…

Diffeomorphic approximation of piecewise affine homeomorphisms

Daniel Campbell, Luigi D'Onofrio, Tomáš Vítek

Given any $f$ a locally finitely piecewise affine homeomorphism of $Ω \subset R^{d}$ onto $Δ \subset R^{d}$ (for $d = 3, 4$ ) such that $f \in W^{1, p} (Ω, R^{d})$ and…
