Graphs defined on groups

PJ Cameron - arxiv preprint arxiv:2102.11177, 2021 - arxiv.org
These notes concern aspects of various graphs whose vertex set is a group $ G $ and
whose edges reflect group structure in some way (so that they are invariant under the action …

The spread of finite and infinite groups

S Harper - arxiv preprint arxiv:2210.09635, 2022 - arxiv.org
It is well known that every finite simple group has a generating pair. Moreover, Guralnick and
Kantor proved that every finite simple group has the stronger property, known as $\frac {3}{2} …

Finite groups satisfying the independence property

SD Freedman, A Lucchini, D Nemmi… - … Journal of Algebra …, 2023 - World Scientific
We say that a finite group G satisfies the independence property if, for every pair of distinct
elements x and y of G, either {x, y} is contained in a minimal generating set for G or one of x …

Some results and questions related to the generating graph of a finite group

A Lucchini, A Maróti - Ischia group theory 2008, 2009 - World Scientific
For a finite group G a graph Γ (G) is defined on the elements of G in such a way that two
distinct vertices are connected by an edge if and only if they generate G. Some results and …
