The number of primes not in a numerical semigroup

Yong-Gao Chen, Hui Zhu

For two coprime positive integers $a$ and $b$ ,let $I ¨ ^{*} (a, b)$ be the number of primes that cannot be represented as $a u + b v$ , where $u$ and $v$ are nonnegative integers. It is cle…

Primes of the form $a x + b y$

Yong-Gao Chen, Hui Zhu

For two coprime positive integers $a, b$ , let $T (a, b) = {a x + b y : x, y \in Z_{\geq 0}}$ and let $s (a, b) = ab - a - b$ . It is well known that all integers which are greater than $s…
