A Littlewood-Offord kind of problem in $Z_{p}$ and $Γ$ -sequenceability

Simone Costa

The Littlewood-Offord problem is a classical question in probability theory and discrete mathematics, proposed, firstly by Littlewood and Offord in the 1940s. Given a set $A$ of in…

Alternating Parity Weak Sequencing

Simone Costa, Stefano Della Fiore

A subset $S$ of a group $(G, +)$ is $t$ -weakly sequenceable if there is an ordering $(y_{1}, \dots, y_{k})$ of its elements such that the partial sums~ $s_{0}, s_{1}, \dots, s_{k}$ , given by…

Weak Heffter Arrays and biembedding graphs on non-orientable surfaces

Simone Costa, Lorenzo Mella, Anita Pasotti

In 2015, Archdeacon proposed the notion of Heffter arrays in view of its connection to several other combinatorial objects. In the same paper he also presented the following varian…

Sequencings in Semidirect Products via the Polynomial Method

Simone Costa, Stefano Della Fiore, M. A. Ollis

The partial sums of a sequence $x = x_{1}, x_{2}, \dots, x_{k}$ of distinct non-identity elements of a group $(G, \cdot)$ are $s_{0} = i d_{G}$ and $s_{j} = \prod_{i = 1}^{j} x_{i}$ for $0…
