Existence of -Fold Non-zero sum Heffter arrays through local considerations
Simone Costa, Stefano Della Fiore
In [12] was introduced, for cyclic groups, the class of partially filled arrays of the non-zero sum Heffter array that are, as the Heffter arrays, related to difference families, g…
Weak Sequenceability in Cyclic Groups
Simone Costa, Stefano Della Fiore
A subset of an abelian group is sequenceable if there is an ordering of its elements such that the partial sums , given by $s_…
On Sequences in Cyclic Groups with Distinct Partial Sums
Simone Costa, Stefano Della Fiore, M. A. Ollis +1
A subset of an abelian group is {\em sequenceable} if there is an ordering of its elements such that the partial sums , given by $y_0…
Vertex-regular -factorizations in infinite graphs
Simone Costa, Tommaso Traetta
The existence of -factorizations of an infinite complete equipartite graph (with parts of size ) admitting a vertex-regular automorphism group is known only…
Factorizing the Rado graph and infinite complete graphs
Simone Costa, Tommaso Traetta
Let be a family of infinite graphs, together with . The Factorization Problem asks whether can be real…
New bounds for perfect -hashing
Simone Costa, Marco Dalai
Let be such that for any distinct elements of there exists a coordinate where they all differ simultaneously. Fredman and Komlós studied upper…
