对于一个由m个正整数构成的数组,若其中任意两个正整数的乘积都等于一个完全平方数减去1,则称这个数组为Diophantine m-tuples.最近,Dujella获得了关于Diophantine2-tuples及3-tuples个数的渐进公式.本文改进了的相关结果.
A set of m positive integers is called a Diophantine m-tuple if the product of any two of them is one less than a perfect square.Recently Dujella derived asymptotic estimates for the number of Diophantine pairs and triples.In this paper we establish some more explicit asymptotic formulas.
