On number of a21 +p21 =p22 +p23≤x
摘要
Abstract
Let r1(n)denote the number of representations of the positive integer n as the sum of a square of a positive integer and the square of a positive prime number,let r2(n)denote the number of representations of the positive integer n as the sum of the squares of two prime numbers.Use S1,2(x)torepresentthemeanvalues∑n≤xr1(n)r2(n).Sedunova calculated x/log2x≪ S1,2(x)≪ x/log2x(loglogx)2.In this paper,the Brun sieve was used to further x improve this result.Proved that when there was x→∞,there was S1,2(x)(())x/log2x.关键词
