Dias da Silva for helping them to improve and revise this article. Learn more about Amazon Prime. Let H be the subgraph of G induced by the vertices of X. Now, we can ask: Thus, for Proposition 2. Linear Algebra 14 32— If a student is not approved by tests, he can still perform the recourse exam. Hogben, Spectral graph theory and the inverse eigenvalue problem of a graph, Electron J. The main result of this section is Theorem 3. Share your thoughts with other customers. More recently, other authors have been studying mr G when G is a graph different from a tree, e.

Math 8 — The latter inequality is a consequence of Proposition 2. This course aims to provide concepts of Linear Algebra, which are of crucial importance to the training of the Electrical Engineering undergraduates. They also would like to thank J. Repeating this process we obtain a contradiction. Systems of Linear Equations and Matrixes; 2. English Choose a language for shopping.

To get a final classification, in the UC, a student must obtain frequency or be excused from that obtention see above, under “Obtaining frequency”. Log In Sign Up. Hogben, Computation of minimal rank and path cover number for graphs, Linear Algebra Appl.

Master in Electrical and Computers Engineering. Being in these conditions, any student can be approved doing the normal tests or the recourse exam. A pendent path incident with algfbra is a path v1v2. Amazon Music Stream millions of songs.

Let G be a graph such that G is a path of order p. Product details Lagebra Publisher: Thus, G has, at most, one pendent path of odd order. Loewy, Graphs whose minimal rank is two: Perdgiao, there exists, at most, one pendent path incident with x of odd order. Click here to sign up. We denote by N x the set of all neighbors of x in G, i. 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.

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 ccecilia until we reach the vertices of the last class Xp. Next we construct the equivalence class graph of G. Fernandesmcds fct.

The fundamental concepts include algebraic structures, linear or vector distance, matrix analysis and linear transformations. Implications to the minimum rank of graphs, Electron.

The theoretical-practical classes aim to better orientate the study of this course by making exercises that apply the taught information. Loewy, Graphs whose minimal rank is two, Electron. As for the evaluation there are four different moments, namely: Amazon Linexr Chance Pass it on, trade it in, give it a second life.

Graphs; Hermitian matrices; Minimum rank 1. Students who have attended to the course in previous years and students with a special status will also be admitted to exams. There are no another classes with cardinality one, so G satisfies the hypothesis of Theorem 3.

Let B be the adjacency matrix of G. In particular when G is an unicyclic graph, the problem was solved in [3].
