Note on the group edge irregularity strength of graphs

Marcin Anholcer, Sylwia Cichacz

We investigate the \textit{edge group irregularity strength} ( $e s_{g} (G)$ ) of graphs, i.e. the smallest value of $s$ such that taking any Abelian group $G$ of order $s$ , th…

Linear bounds on nowhere-zero group irregularity strength and nowhere-zero group sum chromatic number of graphs

Marcin Anholcer, Sylwia Cichacz, Jakub Przybyło

We investigate the \textit{group irregularity strength}, $s_{g} (G)$ , of a graph, i.e. the least integer $k$ such that taking any Abelian group $G$ of order $k$ , there exist…

A magic rectangle set on Abelian groups

Sylwia Cichacz, Tomasz Hinc

A $Γ$ -magic rectangle set $M R S_{Γ} (a, b; c)$ of order $ab c$ is a collection of $c$ arrays $(a \times b)$ whose entries are elements of group $Γ$ , each appearing once, with all row sum…
