Alexander and Thurston norms, and the Bieri-Neumann-Strebel invariants for free-by-cyclic groups

Florian Funke, Dawid Kielak

We investigate Friedl-Lück's universal $L^{2}$ -torsion for descending HNN extensions of finitely generated free groups, and so in particular for $F_{n}$ -by- $Z$ groups. This in…

The integral polytope group

Florian Funke

We show that the Grothendieck group associated to integral polytopes in $R^{n}$ is free-abelian by providing an explicit basis. Moreover, we identify the involution on this…
