Globally simple Heffter arrays $H (n; k)$ when $k \equiv 0, 3 mod 4$

K. Burrage, Nicholas J. Cavenagh, D. Donovan +1

Square Heffter arrays are $n \times n$ arrays such that each row and each column contains $k$ filled cells, each row and column sum is divisible by $2 nk + 1$ and either $x$ or $- x$ ap…

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…
