WebThe Perron-Frobenius theorem tells us that the eigenvalue with largest absolute value is real, and that there is an associated dominant eigenvector, all of whose elements are positive. … WebOct 27, 2012 · By a theorem of Perron and Frobenius, k is a simple eigenvalue with a positive eigenvector u. Now with componentwise absolute value, k x = − kx = Ax ≤ A x . Multiplication with uT shows that we must have equality. Hence x is an eigenvector, hence a multiple of u. Therefore x has no zero component.

WebThe eigenvector centrality for node i is the i -th element of the vector x defined by the equation A x = λ x where A is the adjacency matrix of the graph G with eigenvalue λ. By virtue of the Perron–Frobenius theorem, there is a unique solution x, all of whose entries are positive, if λ is the largest eigenvalue of the adjacency matrix A ( [2] ).
