The intersection Problem for Kite-GDDs of Type 2u
收藏 引用
Journal of Mathematical Research with Applications 2021年 第6期41卷 551-564页
作者: Yonghong AN Guizhi ZHANG College of Continuing Education Hulunbuir University Division of Science and Technology Hulunbuir University
The intersection problem for kite-GDDs is the determination of all pairs(T, s) such that there exists a pair of kite-GDDs(X, H, B) and(X, H, B) of the same type T satisfying|B∩ B| = s. In this paper the interse... 详细信息
