For a sequence of positive integers, let be the set of all integers which can be represented as the finite sum of distinct terms of . In 2012, Chen and Fang proved that, for a sequence of integers , if and for all , then there exists an infinite sequence of positive integers for which ; on the other hand, if , then such does not exist. Recently, for , the authors determined the critical value for such that there exists an infinite sequence of positive integers for which . In this paper, we fix the exact critical values for the above general terms.

对于序列 的正整数,让 是所有整数的集合,可以表示为的不同项的有限和 。在2012年,Chen和Fang证明了,对于整数序列如果 和 对所有人 ,则存在无限序列 正整数的 ; 另一方面,如果,然后这样 不存在。最近,对于,作者确定了 这样就存在一个无限的序列 正整数的 。在本文中,我们为上述一般术语确定了确切的临界值。
