Let $G$ be a group and $mathcal{N}$ be the class of all nilpotent groups. A subset $A$ of $G$ is said to be nonnilpotent if for any two distinct elements $a$ and $b$ in $A$, $langle a, brangle notin mathcal{N}$. If, for any other nonnilpotent subset

For any group $G$, we define an equivalence relation $thicksim$ as below: [forall g, h in G gthicksim h Longleftrightarrow |g|=|h|] the set of sizes of equivalence classes with respect to this relation is called the same

Given the complexity of Search and Rescue (SAR) activities in the coastal regions of Eastern Canada and the Arctic, there is a need to objectively assess system capabilities at a high level to determine the expected rescue time for multiple scenarios

For a finite group G, we define an equivalence relation ∼ on G as follows:∀ x,y∈G x∼y⇔|xG|=|yG|,where xG is the conjugacy class of x in G. The set of sizes of equivalence classes with respect to th...

Let o ( G ) be the average order of the elements of G, where G is a finite group. We show that there is no polynomial lower bound for o ( G ) in terms of o ( N ) , where N ⊴ G , even when G is a prime-power order group and N is abelian. This gives

We show that a finite nonabelian characteristically simple group G satisfies n = ∣π(G)∣ + 2 if and only if G ≅ A5, where n is the number of isomorphism classes of derived subgroups of G and π(G) is the set of prime divisors of the group G. Al

Let G be a group and n a positive integer. We define B n ( G ) {B_{n}(G)} to be the intersection of the normalizers of all the non-n-subnormal subgroups of G. We give a new characterization for nilpotent groups in terms of a series defined via B
