12th May 2008 — Matrix Tree Lemma
Yee Whye is going to go over the proof of the "Matrix Tree Lemma"
The matrix tree theorem, also called Kirchhoff's matrix-tree theorem
(Buekenhout and Parker 1998), states that the number of nonidentical spanning
trees of a graph G is equal to any cofactor of the degree matrix of G minus
the adjacency matrix of G (Skiena 1990, p.235).
