AI总结:

本文证明形如 \\(p+F_{2^k}+F_q\\)(\\(p,q\\) 为素数,\\(k\ge0\\))的整数集合具有正的下渐近密度,同时其补集也具有正的下渐近密度。

摘要:

1934年,Romanoff证明了可表示为素数加2的幂的正整数集合具有正的下密度。Erdős后来构造了一个奇数的无穷等差数列,其中每个数都不能如此表示。设\\(F_n\\)为斐波那契数列。本文证明,形如\\(p+F_{2^k}+F_q\\)(其中\\(p,q\\)为素数,\\(k\ge0\\))的整数集合具有正的下渐近密度。同样,不能表示为这种形式的整数集合也具有正的下渐近密度。

英文摘要:

In 1934, Romanoff proved that the set of positive integers representable as the sum of a prime and a power of two has positive lower density. Erdős later constructed an infinite arithmetic progression of odd integers none of which admits such a representation. Let \(F_n\) be the Fibonacci sequence. In this paper, we prove that the set of integers of the form \(p+F_{2^k}+F_q\), where \(p,q\) are primes and \(k\ge0\), has positive lower asymptotic density. The same holds for the set of integers not of this form.
