Bounding the Number of Hyperedges in Friendship -Hypergraphs
Karen Gunderson, Natasha Morrison, Jason Semeraro
For , an -uniform hypergraph is called a friendship -hypergraph if every set of vertices has a unique 'friend' - that is, there exists a unique vertex $x \no…
Centralizers of normal subgroups and the -Theorem
Ellen Henke, Jason Semeraro
Glauberman's -theorem and analogous statements for odd primes show that, for any prime and any finite group with Sylow -subgroup , the centre of $G/O_{p^\prime}(…
Conway groupoids and completely transitive codes
Nick Gill, Neil I. Gillespie, Jason Semeraro
To each supersimple design one associates a `Conway groupoid,' which may be thought of as a natural generalisation of Conway's Mathieu groupoid associated…
Generating groups using hypergraphs
Nick Gill, Neil I. Gillespie, Anthony Nixon +1
To a set of 4-subsets of a set of size we introduce an invariant called the `hole stabilizer' which generalises a construction of Conway, Elkies and Martin of…
Centralizers of Subsystems of Fusion Systems
Jason Semeraro
When is a -local finite group and is weakly normal in we show that a definition of $C_S…
