Binary Words Containing Few Abelian Squares

Szilard Zsolt Fazekas, Adam Mammoliti, Robert Mercas +1

Fici and Saarela ([2]) conjectured that a binary word of length n contains at least $⌊ n /4 ⌋$ abelian squares. We slightly extend this conjecture and show that it holds…

On the Hamiltonicity, traceability and toughness of complements of line graphs

Adam Mammoliti

A coline graph $co (G)$ of a graph $G$ is the graph with vertex set $E (G)$ for which two vertices $e$ and $e^{'}$ of $co (G)$ are adjacent if and only if they are not adja…

Canonical labelling of Latin squares in average-case polynomial time

Michael J. Gill, Adam Mammoliti, Ian M. Wanless

A Latin square of order $n$ is an $n \times n$ matrix in which each row and column contains each of $n$ symbols exactly once. For $ε > 0$ , we show that with high probability a uniform…

Zarankiewicz numbers near the triple system threshold

Guangzhou Chen, Daniel Horsley, Adam Mammoliti

For positive integers $m$ and $n$ , the Zarankiewicz number $Z_{2, 2} (m, n)$ can be defined as the maximum total degree of a linear hypergraph with $m$ vertices and $n$ edges. Guy det…

Minimising the total number of subsets and supersets

Adam Gowty, Daniel Horsley, Adam Mammoliti

Let $F$ be a family of subsets of a ground set ${1, \dots, n}$ with $∣ F ∣ = m$ , and let $F^{↕}$ denote the family of all subsets of $\{1,\ldo…

Exact values for unbalanced Zarankiewicz numbers

Guangzhou Chen, Daniel Horsley, Adam Mammoliti

For positive integers $s$ , $t$ , $m$ and $n$ , the Zarankiewicz number $Z_{s, t} (m, n)$ is defined to be the maximum number of edges in a bipartite graph with parts of sizes $m$ and $n…

Maximal sets of mutually orthogonal frequency squares

Nicholas J. Cavenagh, Adam Mammoliti, Ian M. Wanless

A frequency square is a square matrix in which each row and column is a permutation of the same multiset of symbols. A frequency square is of type $(n; λ)$ if it contains $n / λ$ symb…

Mutually orthogonal binary frequency squares

Thomas Britz, Nicholas J. Cavenagh, Adam Mammoliti +1

A \emph{frequency square} is a matrix in which each row and column is a permutation of the same multiset of symbols. We consider only {\em binary} frequency squares of order $n$ wi…

Latin squares with maximal partial transversals of many lengths

Anthony B. Evans, Adam Mammoliti, Ian Wanless

A partial transversal $T$ of a Latin square $L$ is a set of entries of $L$ in which each row, column and symbol is represented at most once. A partial transversal is maximal if it…

The cyclic matching sequenceability of regular graphs

Daniel Horsley, Adam Mammoliti

The cyclic matching sequenceability of a simple graph $G$ , denoted $cms (G)$ , is the largest integer $s$ for which there exists a cyclic ordering of the edges of $G$ so tha…

The $r$ -matching sequencibility of complete multi- $k$ -partite $k$ -graphs

Adam Mammoliti

Alspach [{\sl Bull. Inst. Combin. Appl.}~{\bf 52} (2008), 7--20] defined the maximal matching sequencibility of a graph $G$ , denoted~ $m s (G)$ , to be the largest integer $s$ for whic…

Intersection theorems for families of matchings of complete $k$ -partite $k$ -graphs

Adam Mammoliti

The celebrated {Erdős-Ko-Rado} Theorem states that for $n \geq 2 k$ a family $F$ of $k$ subsets of $[n]$ for which each pair of members of $F$ have a non-empty i…

Balanced diagonals in frequency squares

Nicholas Cavenagh, Adam Mammoliti

We say that a diagonal in an array is {\em $λ$ -balanced} if each entry occurs $λ$ times. Let $L$ be a frequency square of type $F (n; λ^{m})$ ; that is, an $n \times n$ array in which ea…

On Mubayi's Conjecture and conditionally intersecting sets

Adam Mammoliti, Thomas Britz

Mubayi's Conjecture states that if $F$ is a family of $k$ -sized subsets of $[n] = {1, \dots, n}$ which, for $k \geq d \geq 2$ , satisfies $A_1 \cap\cdots\cap A_d \neq \em…
