A characterisation of weakly locally projective amalgams related to $A_{16}$ and the sporadic simple groups $M_{24}$ and $H e$

Michael Giudici, A. A. Ivanov, Luke Morgan +1

A simple undirected graph is weakly $G$ -locally projective, for a group of automorphisms $G$ , if for each vertex $x$ , the stabiliser $G (x)$ induces on the set of vertices adjacent…

On locally semiprimitive graphs and a theorem of Weiss

Michael Giudici, Luke Morgan

In this paper we investigate graphs that admit a group acting arc-transitively such that the local action is semiprimitive with a regular normal nilpotent subgroup. This type of se…

A class of semiprimitive groups that are graph-restrictive

Michael Giudici, Luke Morgan

We prove that an infinite family of semiprimitive groups are graph-restrictive. This adds to the evidence for the validity of the PSV Conjecture and increases the minimal imprimiti…
