Properties of the Fibonacci-sum graph

Andrii Arman, David S. Gunderson, Pak Ching Li

For each positive integer $n$ , the Fibonacci-sum graph $G_{n}$ on vertices $1, 2, \dots, n$ is defined by two vertices forming an edge if and only if they sum to a Fibonacci number. It…

Cycle-maximal triangle-free graphs

Stephane Durocher, David S. Gunderson, Pak Ching Li +1

We conjecture that the balanced complete bipartite graph $K_{⌊ n /2 ⌋, ⌈ n /2 ⌉}$ contains more cycles than any other $n$ -vertex triangle-free graph, and we make…

Sperner partition systems

P. C. Li, Karen Meagher

A \textsl{Sperner $k$ -partition system} on a set $X$ is a set of partitions of $X$ into $k$ classes such that the classes of the partitions form a Sperner set system (so no class f…
