Davenport constant and its variants for some non-abelian groups

C. G. Karthick Babu, Ranjan Bera, Mainak Ghosh +1

We define two variants $e (G)$ , $f (G)$ of the Davenport constant $d (G)$ of a finite group $G$ , that is not necessarily abelian. These naturally arising constants aid in computing $d…
