Perron frobenius eigenvector

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.
