关于有限II的限制Prime Factors的个数

On the Number of Restricted Prime Factors of an Integer II

Alexander P. Mangerel

摘要:

给定素数集的一个划分$\{E_0,\ldots,E_n\}$和一个向量$\mathbf{k} \in \mathbb{N}_0^{n+1}$,我们计算了数量$|\{m \leq x: ω_{E_j}(m) = k_j \ \forall \ 0 \leq j \leq n\}|$在很宽的参数$k_j$范围内一致的渐近公式,补充了作者以前的一篇论文的结果.这是通过使用Wirsing定理的扩展和推广来实现的,该定理给出了比率$\frac{|M_g(x)|}{M_{f}(x)}$的明确估计,无论何时$f: \mathbb{N} \rightarrow (0,\infty)$和$g: \mathbb{N} \rightarrow \mathbb{C}$是强乘法函数,它们在素数上一致有界,并且对于每个$n \in \mathbb{N}$都满足$|g(n)| \leq f(n)$。这也允许我们得出结论的有效性概率启发式关于$π(x;\mathbf{E},\mathbf{k})$的情况下,$k_j = (1+o(1))E_j(x)$,对于每个$0 \leq j \leq n$。

英文摘要:

Given a partition $\{E_0,\ldots,E_n\}$ of the set of primes and a vector $\mathbf{k} \in \mathbb{N}_0^{n+1}$, we compute an asymptotic formula for the quantity $|\{m \leq x: ω_{E_j}(m) = k_j \ \forall \ 0 \leq j \leq n\}|$ uniformly in a wide range of the parameters $k_j$ that complements the results of a previous paper of the author. This is accomplished using an extension and generalization of a theorem of Wirsing due to the author that gives explicit estimates for the ratio $\frac{|M_g(x)|}{M_{f}(x)}$, whenever $f: \mathbb{N} \rightarrow (0,\infty)$ and $g: \mathbb{N} \rightarrow \mathbb{C}$ are strongly multiplicative functions that are uniformly bounded on primes and satisfy $|g(n)| \leq f(n)$ for every $n \in \mathbb{N}$. This also allows us to conclude the validity of a probabilistic heuristic regarding $π(x;\mathbf{E},\mathbf{k})$ in the case that $k_j = (1+o(1))E_j(x)$, for each $0 \leq j \leq n$.
