Locating eigenvalues in trees
Witrynadeveloped an algorithm to locate eigenvalues of any perturbed Laplacian matrix of an edge-weighted tree, called DiagonalizeW. Given a real diagonal matrix D , the perturbed Laplacian matrix of a simple graph G with respect to D is the matrix L D ( G ) = D - A , where A = ( a i j ) is the adjacency matrix of G . Witryna204 Y. Hou, J. Li / Linear Algebra and its Applications 342 (2002) 203–217 graph-theoretic properties of G and its eigenvalues. Up to now, the eigenvalues of a tree T with a perfect matching have been studied by several authors (see [2,7,8]). However, when a tree has no perfect matching but has an m-matching M, namely, M consists of …
