We examine the family of graphs whose complements are a union of paths and cycles and develop a very simple algebraic technique for comparing the number of spanning trees. With our algebra, we can obtain a simple proof of a result of Kel'mans that evening out path lengths increases the number of spa

## Abstract It is an NPβcomplete problem to decide whether a graph contains a spanning tree with no vertex of degree 2. We show that these homeomorphically irreducible spanning trees are contained in all graphs with minimum degree at least __c__β__n__ and in triangulations of the plane. They are ne
