设c〉0是一个非整数实数,x是一个充分大实数.令Nc(x)表示不超过x且满足(n,[n^c])=1的自然数n的个数,本文得到了Nc(x)的渐近公式,改进了Delmer和Deshouillers的结果.
Let c 〉 1 be a fixed real number which is not an integer and x be a large real number. Let Nc(x) be the number of natural numbers n not exceeding x such that (n, [n^c]) = 1. In this paper we get an asymptotic formula of Nc(x), which further improves a result of Delmer and Deshouillers.
