1) zero-sum subsequence
零和子列
1.
We disprove a conjecture concerning zero-sum problem by showing the following, Let p> l0000be a prime with p 3(mod4) , and let S = be a sequence of pelements in Zp, Then, there is no sequence T of p elements in Z, such that f,(T) f,(S) and T has at most two distinct nonzero terms, where fp(S) denote the number of zero-sum subsequences of S
本文证明了下述结论: 设p>10000为一素数且合于p 3(mod 4),取S(2,3)为Zp,上PA项序列,则不存在 Z,上 p 项序列 T,使得且T的非零项最多有两项互异,其中,fp(S)表示S的零和子列的个数,这一结论否定了一个有关零和问题的猜想
