Kneserized Anticoncentration and Reverse Absorption for Graham's Rearrangement Conjecture

Simone Costa, Stefano Della Fiore, Tao Feng +1

We establish a Kneser-based anticoncentration estimate for uniform subset sums in composite cyclic groups. The estimate contains a periodic loss and is weaker than its prime-modulu…

A note on vector trifferent codes over the Sphere

Stefano Della Fiore

Let $S^{2} \subset R^{3}$ be the unit sphere. A set $C \subset (S^{2})^{n}$ is called vector trifferent if for every three distinct $x, y, z \in C$ there is a coordinate $i$ for which $…

Slice and Partition Rank Criteria for Polynomial Zero-Avoidance

Simone Costa, Stefano Della Fiore, Mattia Fontana

We study polynomial zero-avoidance over finite vector spaces by means of slice rank and partition rank. We first make the support-entropy method effective by showing how a finite d…

Weak Freiman isomorphisms and sequencings of small sets

Simone Costa, Stefano Della Fiore

In this paper, we introduce a weakening of the Freiman isomorphisms between subsets of non necessarily abelian groups. Inspired by the breakthrough result of Kravitz, [14], on cycl…
