无限赋权图中的强极大匹配

Strongly maximal matchings in infinite weighted graphs

Ron Aharoni, Eli Berger, Agelos Georgakopoulos, Philipp Sprüssel

摘要:

给定图G的边的权w,称G中的匹配M是强w-极大的,如果对于任意匹配N,N \M中的边的权之和至多是M \N中的边的权之和.我们证明了,如果w仅假设n个值都是有理数,则G有强w-极大匹配。

英文摘要:

Given an assignment of weights w to the edges of a graph G, a matching M in G is called strongly w-maximal if for any matching N the sum of weights of the edges in N\M is at most the sum of weights of the edges in M\N. We prove that if w assumes only finitely many values all of which are rational then G has a strongly w-maximal matching.
