A note on near alternating sign matrices with prescribed row and column weights
Tommaso Traetta
We study near alternating sign matrices with prescribed row and column weights. After recalling the basic definitions and the necessary conditions coming from the Gale--Ryser theor…
Characterizing pyramidal Hadamard designs with the largest number of fixed points
Tommaso Traetta
A symmetric -design is said to be -pyramidal, with , under the action of a group if acts as an automorphism group fixing points and acting sharply tr…
On circular external difference families
A. Burgess, F. Merola, T. Traetta
Circular external difference families (CEDFs) are a recently-introduced variation of external difference families (EDFs) with applications to non-malleable threshold schemes: a $(v…
The existence of pyramidal Steiner triple systems over abelian groups
Yanxun Chang, Tommaso Traetta, Junling Zhou
A Steiner triple system STS is called -pyramidal if it has an automorphism group fixing points and acting sharply transitively on the remaining points. In this pa…
Towards a solution of Archdeacon's conjecture on integer Heffter arrays
Marco Antonio Pellegrini, Tommaso Traetta
In this paper, we make significant progress on a conjecture proposed by Dan Archdeacon on the existence of integer Heffter arrays whenever the necessary conditions hol…
A sharp upper bound for the harmonious total chromatic number of graphs and multigraphs
M. Abreu, J. B. Gauci, D. Mattiolo +4
A proper total colouring of a graph is called harmonious if it has the further property that when replacing each unordered pair of incident vertices and edges with their colour…
