本文首先讨论了二部图中双单纯边与概念格中概念之间的对应关系;其次研究了弦二部图和约简的形式背景的若干性质;最后将概念格中元素的消除理论应用于二部图的研究
给出了弦二部图的概念格刻画.结果表明
一个二部图是弦二部图当且仅当对应的概念格中有一个不可约元的完美消除序列.
In this paper
the relation between bisimplicial edges in a bipartite graph and their corresponding concepts are discussed
and some properties of reduced contexts and chordal bipartite graphs are investigated.Then
we apply the element elimination for a concept lattice to bipartite graph theory
and obtain a representation of chordal bipartite graphs.More precisely
we show that a bipartite graph is chordal bipartite graph if and only if there is a join and meet irreducible element elimination ordering with respect to its corresponding concept lattice.
