  • Abstract
    We obtain an explicit formula for the absolute difference between two eigenvector components for a weighted graph´s Laplacian matrix, in terms of the the Laplacian´s eigenvalues as well as the eigenvalues of matrices associated with certain coalesced graphs. We then briefly illustrate two uses of this formula, in analyzing graph modifications.
