WebCounting Spanning Trees⁄ Bang Ye Wu Kun-Mao Chao 1 Counting Spanning Trees This book provides a comprehensive introduction to the modern study of spanning trees. A span-ning tree for a graph G is a subgraph of G that is a tree and contains all the vertices of G. There are many situations in which good spanning trees must be found.
