Matching Preclusion of the Generalized Petersen Graph
Ajay Arora, Eddie Cheng, Christopher Melekian · Theory and Applications of Graphs · 2019
The matching preclusion number of a graph with an even number of vertices is the minimum number of edges whose deletion results in a graph with no perfect matchings. In this paper we determine the matching preclusion number for the generalized Petersen graph $P(n,k)$ and classify the optimal sets.
