Normal $2$ -coverings of the finite simple groups and their generalizations

Daniela Bubboloni, Pablo Spiga, Thomas Weigel

Given a finite group $G$ , we say that $G$ has weak normal covering number $γ_{w} (G)$ if $γ_{w} (G)$ is the smallest integer with $G$ admitting proper subgroups $H_{1}, \dots, H_{γ_{w} (G)}$ s…

On the second cohomology of the norm one group of a p-adic division algebra

Mikhail Ershov, Thomas Weigel

Let $F$ be a $p$ -adic field, that is, a finite extension of $Q_{p}$ . Let $D$ be a finite-dimensional central division algebra over $F$ and let $S L_{1} (D)$ be the group of eleme…

Unimodular totally disconnected locally compact groups of rational discrete cohomological dimension one

Ilaria Castellano, Bianca Marchionna, Thomas Weigel

It is shown that a Stallings--Swan theorem holds in a totally disconnected locally compact (= t.d.l.c.) context (cf. Thm. B). More precisely, a compactly generated $C O$ -b…
