A closer look at the non-Hopfianness of $B S (2, 3)$

Tom Kaiser

The Baumslag-Solitar group $B S (2, 3)$ , is a so-called non-Hopfian group, meaning that it has an epimorphism $ϕ$ onto itself, that is not injective. In particular this is equivalent…

Magnitude Homology, Diagonality, Medianness, Künneth and Mayer-Vietoris

Rémi Bottinelli, Tom Kaiser

Magnitude homology of graphs is introduced by Hepworth and Willerton in arXiv:1505.04125 . Magnitude homology of arbitrary metric spaces by Leinster and Shulman in arXiv:1711.00802…

The first uniformly finite homology group with coefficients in $Z$ and a characterisation of its vanishing in the transitive case

Rémi Bottinelli, Tom Kaiser

We study the first uniformly finite homology group of Block and Weinberger for uniformly locally finite graphs, with coefficients in $Z$ and $Z_{2}$ . When the graph…
