Polignac's conjecture: Derivation of a Mathematical Formula cnXiv    by Jian Hu,

波利尼亚克猜想:数学表达式的一个推导 cnxiv  作者:胡坚 

Abstract: With using the segmented Eratosthenes' sieve approach, a definite mathematical formula describing Polignac's conjecture, p_(k+1)=p_k+2h, is deduced from a newly uncovered unusual distribution of prime numbers in the p_k~l_k plot (l_k is the segment length and p_k the prime number), where the parameter h is a positive integer unique to prime numbers. Validity of the said formula is proved by mathematical induction.

Keywords: number theory, Polignac's conjecture, sieve of Eratosthenes, formula.
