For the sake of simplicity, consider an ordering of the elements of V G such that each equivalence class of R is a set of consecutive elements in that ordering; for instance first we consider the vertices of X1then the vertices of X2and so on until we reach the vertices of the last class Xp.

Hence B is singular, contradicting our hypothesis. In Section 3 we study the previous inequality for all graphs whose equivalence class graph is a path. There are no another classes with cardinality one, so G satisfies the hypothesis of Theorem 3.
