摘要: 设G是含有完美匹配的简单图. 称图G是偶匹配可扩的(BM-可扩的), 如果G的每一个导出子图是偶图的匹配M都可以扩充为一个完美匹配. 极图问题是图论的核心问题之一. 本文将刻画极大偶匹配不可扩图, 偶图图类和完全多部图图类中的极大偶匹配可扩图.
Abstract: Let $G$ be a simple graph containing a perfect matching. $G$ is said to be bipartite matching extendable (BM-extendable) if every matching $M$ whose induced subgraph is a bipartite graph extends to a perfect matching. Extremal graph problems are at the core of graph theory. In this paper, we characterize maximally BM-unextendable graphs, maximally BM-extendable graphs in the class of complete $k$-partite graphs with $k\geq 2$.
