Presenting the Zassenhaus Lie algebra by the Magnus Lie algebra

Ettore Marmo, David Riley, Thomas Weigel

It is shown that the Zassenhaus restricted $F_{p}$ -Lie algebra of a (pro-p) group G can be presented by the Magnus Lie algebra of G. For the class of (pro-p) groups for which…

Toric arrangements and Bloch-Kato pro- $p$ groups

Emanuele Delucchi, Ettore Marmo

We prove a purely combinatorial obstruction for the Bloch-Kato property within the class of fundamental groups of complement manifolds of toric arrangements (i.e., arrangements of…

Sharpness of saturated fusion systems on a Sylow $p$ -subgroup of $G_{2} (p)$

Valentina Grazian, Ettore Marmo

We prove that the Díaz-Park's sharpness conjecture holds for saturated fusion systems defined on a Sylow $p$ -subgroup of the group $G_{2} (p)$ , for $p \geq 5$ .
