p-Groups in which kernels of the non-linear irreducible characters are of equal order

Nabajit Talukdar

For an irreducible character $χ$ of a finite group $G$ , its kernel is defined as $ker χ = {g \in G : χ (g) = χ (1)}$ . In this paper we characterize the finite groups of prime powe…

Cut edges and Central vertices of zero divisor graph of the ring of integers modulo n

Nabajit Talukdar

The zero divisor graph of a commutative ring $R$ with unity is a graph whose vertices are the nonzero zero-divisors of the ring, with two distinct vertices being adjacent if their…

Some results on GVZ-groups with two character degrees

Nabajit Talukdar, Kukil Kalpa Rajkhowa

We investigate the finite groups $G$ for which $χ (1)^{2} = ∣ G : Z (χ) ∣$ for all characters $χ \in I r r (G)$ and $∣ c d (G) ∣ = 2$ , where $c d (G) = {χ (1) ∣ χ \in I r r (G)}$ . We call such a group a GVZ…
