A Note on the Asymptotic Least Density of Covering Codes in $[q]^{n}$

Andrey Shapiro

In this short note we revisit the upper bound of the asymptotic least density of covering codes of radius $R$ in $[q]^{n}$ established by Krivelevich, Sudakov, and Vu. We show that b…

A linear upper bound on zero-sum Ramsey numbers of $d$ -degenerate graphs in $Z_{p}$

Andrey Shapiro

Let $p$ be a prime number and let $G$ be a graph on $n$ vertices and $m$ edges. The zero-sum Ramsey number of $G$ over $Z_{p}$ , denoted by $R (G, Z_{p})$ , is the minim…
