cyclotomy
解釋
分割圓法-
This book is composed of following sections : in the first section, we present the nessary definitions and give a well - rounded treatment of known families of almost difference sets ; in the second section, we discuss the possibility of constructing almost difference sets with 2, 4 and 6 order cyclotomy classes ; in the third section, we construct two new families of almost difference sets by using cyclotomy modulo pq, where p and q are distinct primes ; in the last section, we discuss the methord to construct almost difference sets with difference sets
然而即使這樣，已發現的幾乎差集還是很有限。本文由以下四個部分組成：第一部分給出必要的定義和綜述；第二部分就2階、 4階及6階分圓類可能構成幾乎差集的情形給于討論；第三部分利用模pq （ p ， q為互異素數）分圓類構造了兩類新的幾乎差集；第四部分討論了由差集構造幾乎差集的方法。
