设A,B是有限幂零群G的两个非空子集.若$A\not=B$,则限制和集$$A\dotplus B={a+B:a\in A,B\in B,a\neq B} $$的基数至少为$$\min{p(G),|一|+|B|-2},$$其中$p(G)$表示$|G| $.
Suppose that $A,B$ are two non-empty subsets of the finite nilpotent group $G$. If $A\not=B$, then the cardinality of the restricted sumset $$A\dotplus B={a+b: a\in A, b\in B, a\neq b} $$ is at least $$\min{p(G),|A|+|B|-2},$$ where $p(G)$ denotes the least prime factor of $|G|$.
