On the Order of Products of Coprime Elements in Finite Groups

M. Amiri, I. Lima, S. Sousa

In this work, we introduce the subgroups $D_{m} (G)$ and $D_{m, n} (G)$ , defined in terms of the orders of products of coprime elements in a finite group $G$ . We show that both subgroup…

On the structure of $L C$ -nilpotent groups

M. Amiri, I. Kashuba, I. Lima

For a finite group $G$ , let $L C (G)$ be the subgroup generated by elements $x$ such that, for all $y \in G$ and all integers $n$ , the order of $x^{n} y$ divides the least common multi…

Maximal covers of finite groups

Igor Lima, Raimundo Bastos, José R. Rogério

Let $λ (G)$ be the maximum number of subgroups in an irredundant covering of the finite group $G$ . We prove that if $G$ is a group with $λ (G) ⩽ 6$ , then $G$ is supersolvable…
