论文摘要
让$ a $是正整数$ d> 1 $的有限多动力。我们描述了$ a $的所有款式的$ \ mathrm {span}(a)$的结构,尤其是给出$ \ mathrm {spanrm {span}(a)= \ mathrm {spanrm {spanrm {span}(b)$的标准。
Let $A$ be a finite multiset of powers of a positive integer $d>1$. We describe the structure of the set $\mathrm{span}(A)$ of all sums of submultisets of $A$, and in particular give a criterion of $\mathrm{span}(A)=\mathrm{span}(B)$ for two multisets $A,B$.
