The cycle polynomial of a permutation group

Peter J. Cameron, Jason Semeraro

The cycle polynomial of a finite permutation group $G$ is the generating function for the number of elements of $G$ with a given number of cycles: \[F_G(x) = \sum_{g\in G}x^{c(g)},…

Tournaments, 4-uniform hypergraphs, and an exact extremal result

Karen Gunderson, Jason Semeraro

We consider $4$ -uniform hypergraphs with the maximum number of hyperedges subject to the condition that every set of $5$ vertices spans either $0$ or exactly $2$ hyperedges and giv…

Bounding the Number of Hyperedges in Friendship $r$ -Hypergraphs

Karen Gunderson, Natasha Morrison, Jason Semeraro

For $r \geq 2$ , an $r$ -uniform hypergraph is called a friendship $r$ -hypergraph if every set $R$ of $r$ vertices has a unique 'friend' - that is, there exists a unique vertex $x \no…
