Extensions of the Scherck-Kemperman Theorem

Y. O. Hamidoune

Let $Γ = (V, E)$ be a reflexive relation with a transitive automorphisms group. Let $v \in V$ and let $F$ be a finite subset of $V$ with $v \in F .$ We prove that the size of $Γ (F)$ (the…

Distinct Matroid Base Weights and Additive Theory

Y. O. Hamidoune, I. P. da Silva

Let $M$ be a matroid on a set $E$ and let $w : E ⟶ G$ be a weight function, where $G$ is a cyclic group. Assuming that $w (E)$ satisfies the Pollard's Condition (i.e. Eve…

Distinct Lengths Modular Zero-sum Subsequences: A Proof of Graham's Conjecture

Weidong Gao, Y. O. Hamidoune, Guoqing Wang

Let $n$ be a positive integer and let $S$ be a sequence of $n$ integers in the interval $[0, n - 1]$ . If there is an $r$ such that any nonempty subsequence with sum $\equiv 0$ $\pmod…

Extensions of the Moser-Scherck-Kemperman-Wehn Theorem

Yahya Ould Hamidoune

Let $Γ = (V, E)$ be a reflexive relation having a transitive group of automorphisms and let $v \in V .$ Let $F$ be a subset of $V$ with $F \cap Γ^{-} (v) = {v}$ . (i) If $F$ is finite, then…
