PPT-Edge-disjoint induced subgraphs with given minimum

degree Raphael Yuster 2012 Problems concerning edgedisjoint subgraphs that share some specified property are extensively studied in graph theory Many fundamental problems can be formulated in this . A minimum spanning tree is a connected subgraph of G that spans all vertices at minimum cost The number of edges in the minimum spanning tree is Figure 6b is the minimum spanning tree of the graph in Figure 6a In this case the minimum spanning tree 1 Introduction All graphs in this paper are 64257nite and simple Given two graph s and we say that is an induced subgraph of if and two vertices of are adjacent if and only if they are adjacent in Let be a possibly in64257nite family of graphs A Jiao Tong University .
