It is now easy to see that the rows of A corresponding to vertices in the same equivalence class are equal.

Loewy, Graphs whose minimal rank is two: In theoretical classes important concepts and associated results will be presented, giving special emphasis to geometrical interpretations and their practical applications. 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.

Aiming to clarify the definitions and theorems presented, demonstrations will be given each and every time that these might help to achieve that understanding and the students will be given illustrative exercises to solve. Projections and Orthogonality; 5. Wiener, Spectral multiplicity and splitting results for a class of qualitative matrices, Linear Algebra Appl. To get a final classification, in the UC, a student must obtain frequency or be excused from that obtention see above, under “Obtaining frequency”.
