The Structure of Large Sets of Disjoint Extended Mendelsohn Triple
摘要/Abstract
摘要:
Mendelsohn三元系大集(LMTS)是一类有向设计的大集,它的存在性问题已完全解决.若在以上的设计中要求有序对(x,x)也出现,则称这样的设计为extended Mendelsohn三元系大集(LEMTS).给出了LEMTS的构造,从而完全解决了LEMTS的存在性问题.
Abstract:
Large set of pairwise disjoint Mendelsohn triple systems(LMTS) is a kind of large set of oriented design.The existence of LMTS has been proved.The kind of large set above-mentioned is called large set of pairwise disjoint extended Mendelsohn triple systems(LEMTS) if oriented pair(x,x)occurs in them.The structure of LEMTS(v) is proved and the existence of LEMTS is obtained.
