Motivated by Problem 164 proposed by Y. Berkovich and E. Zhmud' in their book "Characters of Finite Groups", we give a characterization of finite groups whose irreducible character codegrees are prime powers. This ...
Let G be a finite group with order g and S be a subring of the algebraic number field which contains the integral extension over Z generated by a g-th primitive root co of unity, and R(G) be the character ring of G....
It is proved that if the degree of any non-linear irreducible character of a finite group G is a product of powers of two given distinct prime integers p and q, then G has an abelian Hall {p, q} subgroup H and an Abel...
