Characterizations of Consistent Marked Graphs

Authors: Fred S. Roberts and Shaoji Xu


A marked graph is a graph with a + or - sign on each vertex and is called consistent if each cycle has an even number of - signs. This concept is motivated by problems of communication networks and social networks. We present some new characterizations/recognition algorithms for consistent marked graphs.
