Biembeddings of cycle systems using integer Heffter arrays

Nicholas J. Cavenagh, D. Donovan, E. Ş. Yazici

In this paper we will show the existence of a face $2$ -colourable biembedding of the complete graph onto an orientable surface where each face is a cycle of a fixed length $k$ , for…

The existence of square non-integer Heffter arrays

Nicholas J. Cavenagh, Jeff Dinitz, Diane Donovan +1

A Heffter array $H (n; k)$ is an $n \times n$ matrix such that each row and column contains $k$ filled cells, each row and column sum is divisible by $2 nk + 1$ and either $x$ or $- x$ ap…

Uniformly resolvable $(C_{4}, K_{1, 3})$ -designs of order $v$ and index $2$

M. Gionfriddo, S. Kucukcifci, S. Milici +1

In this paper we consider the uniformly resolvable decompositions of the complete graph $2 K_{v}$ into subgraphs where each resolution class contains only blocks isomorphic to the sam…
