Finite groups with coprime non-linear codegrees
Ashkan Zarezadeh, Behrooz Khosravi, Zeinab Akhlaghi
Given a finite group G with an irreducible character χ\in Irr(G), the codegree of χis defined by cod(χ) = |G :\ker χ|/χ(1). The set of non-linear irreducible character codegrees of…

Characterizing some finite groups by the average order
Ashkan Zarezadeh, Behrooz Khosravi, Zeinab Akhlaghi
The average order of a finite group G is denoted by o(G). In this note, we classify groups whose average orders are less than o(S4), where S4 is the symmetric group on four element…
