具有限制度和匹配数的图

Graphs with restricted valency and matching number

Niranjan Balachandran, Niraj Khare

摘要:

考虑具有最大度$Δ(G)<d$和匹配数$ν(G)<m$的有限图族。本文给出了这类图的边数的精确上界的一个新的证明,并刻画了极大图唯一的所有情形。我们还对因子临界图的Gallai引理给出了一个新的证明。

英文摘要:

Consider the family of all finite graphs with maximum degree $Δ(G)<d$ and matching number $ν(G)<m$. In this paper we give a new proof to obtain the exact upper bound for the number of edges in such graphs and also characterize all the cases when the maximal graph is unique. We also provide a new proof of Gallai's lemma concerning factor critical graphs.
