摘要: 得到部分差集的p-秩的一个结果:设q≡1(mod 4)是素数幂,p是素数使得p|(q-1)/4。则有限域GF (q)中的二次剩余部分差集的p-秩是(q-1)/2.

Abstract: The author has obtained a result about the p-rank of partial difference sets: let q≡1 (mod 4) be a prime power, p be a prime such that p|(q-1)/4. Then the p-rank of the quadratic residue partial difference set in the field GF (q) is (q-1)/2.

Key words: partial difference set, characters, rank
