The coprime graph of a group
(University of Isfahan, 2014-09-01)The coprime graph $gg$ with a finite group $G$ as follows: Take $G$ as the vertex set of $gg$ and join two distinct vertices $u$ and $v$ if $(|u|,|v|)=1$. In the paper, we explore how the graph theoretical ...

On $n$-Kappe groups
(University of Isfahan, 2014-09-01)Let $G$ be an infinite group and $nin {3, 6}cup{2^k| kin mathbb{N}}$. In this paper, we prove that $G$ is an $n$-Kappe group if and only if for any two infinite subsets $X$ and $Y$ of $G$, there exist $xin X$ and ...

On the total character of finite groups
(University of Isfahan, 2014-09-01)For a finite group $G$, we study the total character $tau_G$ afforded by the direct sum of all the non-isomorphic irreducible complex representations of $G$. We resolve for several classes of groups (the Camina ...
