论文摘要
令Pr $ [n] $是其顶点为$ 2,3,\ ldots,n $的图形,n $,带顶点$ v $,当时为顶点$ w $,并且仅当$ \ gcd(v,w)> 1 $。结果表明,$π(n)$,不超过$ n $的数量,等于此图的lovász数量。该结果提出了用于数字理论问题的图理论研究的新途径。
Let PR$[n]$ be the graph whose vertices are $2,3,\ldots,n$ with vertex $v$ adjacent to vertex $w$ if and only if $\gcd(v,w)>1$. It is shown that $π(n)$, the the number of primes no more than $n$, equals the Lovász number of this graph. This result suggests new avenues for graph-theoretic investigations of number-theoretic problems.
