Minimal partition-free groups

Afsane Bahri, Zeinab Akhlaghi, Behrooz Khosravi

Let G be a finite group. A collection P={H1, ..., Hr} of subgroups of G, where r > 1, is said a non-trivial partition of G if every non-identity element of G belongs to one and onl…

Equivalent version of Huppert's conjecture on the codegrees

Afsane Bahri, Zeinab Akhlaghi, Behrooz Khosravi

Let G be a finite group, Irr(G) the set of all irreducible complex characters of G and X \in Irr(G). Let also cod(X) = |G : kerX|/X(1) and cod(G) = {cod(X) | X \in Irr(G)}. In this…

A result on the sum of element orders of a finite group

Afsaneh Bahri, Behrooz Khosravi, Zeinab Akhlaghi

Let $G$ be a finite group and $ψ (G) = \sum_{g \in G} o (g)$ . There are some results about the relation between $ψ (G)$ and the structure of $G$ . For instance, it is proved that if $G$ …
