Induced Matching Extendability of Claw-free Graphs of Diameter 2
摘要
Abstract
A simple graph G is induced matching extendable,shortly IM-extendable,if every induced matching of G is included in a perfect matching of G.The induced matching extendability of claw-free graphs of diameter 2 is studied.It is shown that a claw-free graph G of diameter 2 is IM-extendable if and only if,for any induced matching M with |M|≤3 of G,G-V(M) has no odd component.Consequently,the IM-extendability problem of claw-free graphs of diameter 2 is polynomially solvable.
