Bounds and Limitations on Codes Achieving List Recovery Capacity

Joshua Brakensiek, Yeyuan Chen, Aaron Putterman +1

In coding theory, list recoverability is a fundamental concept which robustly captures how ``spread-out'' codewords are in a code. More formally, given a code $C \subseteq I^£^{n}$ an…

Cross representations of additive complements of $r$ -th powers

Yuchen Ding, Ben Krause, Csaba SÃ¡ndor +2

Let $N$ be the set of natural numbers and $S_{r} = {1^{r}, 2^{r}, 3^{r}, \dots}$ the set of $r$ -th powers, where $r \geq 2$ is a natural number. Let $\mathcal{W}_r…

An Improvement of Konstantoulas' Density Constant

Huixi Li, Zihan Zhang

Let $A \subset N$ , and define its ordered representation function $r (n) = # {(a, b) \in A \times A : a + b = n} .$ The Erdos--Turan conjecture asserts that, if $r (n) > 0$ for all sufficiently…
