Several authors have been interested on the multiplicity of the eigenvalues of the matrices whose graph is a tree, e. 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 X2 and so on until we reach the vertices of the last class Xp.

Shopbop Designer Fashion Brands. Thus, G has, at most, one pendent path of odd order. Students who are under special statutes TE, DA, In theoretical classes important concepts and associated results will be presented, giving special emphasis to geometrical interpretations and their practical applications. It is now easy to see that the rows of A corresponding to vertices in the same equivalence class are equal. Log In Sign Up. The theoretical-practical classes aim to better orientate the study of this course by making exercises that apply the taught information.
