On irreducibility of induced modules and an adaptation of the Wigner--Mackey method of little groups

Geetha Venkataraman

This paper deals with sufficiency conditions for irreducibility of certain induced modules. We also construct irreducible representations for a group $G$ over a field $K$ …

On finite groups whose every proper normal subgroup is a union of a given number of conjugacy classes

Ali Reza Ashrafi, Geetha Venkataraman

Let $G$ be a finite group and $A$ be a normal subgroup of $G$ . We denote by $n cc (A)$ the number of $G$ -conjugacy classes of $A$ and $A$ is called $n$ -decomposable, if $n cc (A) = n$ . S…
