2018-12-11 10:00-11:00 FAMNIT-Muzejski3 Luke Morgan Semiprimitive groups and the graph-restrictive property The Weiss Conjecture has stimulated much study of symmetric graphs, especially concerning the order of vertex-stabilisers. The conjecture roughly asserts that in a locally-primitive symmetric graph, the vertex-stabiliser is…
