Locating eigenvalues of perturbed laplacian matrices of trees
(2017) [Artículo de periódico]We give a linear time algorithm to compute the number of eigenvalues of any perturbed Laplacian matrix of a tree in a given real interval. The algorithm can be applied to weighted or unweighted trees. Using our method we ...
