Abstract

A spanning subgraph F of a graph G is called perfect if F is a forest, the degree inline image of each vertex x in F is odd, and each tree of F is an induced subgraph of G. We provide a short linear-algebraic proof of the following theorem of A. D. Scott (Graphs Combin 17 (2001), 539–553): A connected graph G contains a perfect forest if and only if G has an even number of vertices.
