Isospectral Graph Reductions and Improved Estimates of Matrices' Spectra
L. A. Bunimovich, B. Z. Webb
Via the process of isospectral graph reduction the adjacency matrix of a graph can be reduced to a smaller matrix while its spectrum is preserved up to some known set. It is then p…

Isospectral Graph Reductions
Leonid Bunimovich, Benjamin Webb
Let G be an arbitrary finite weighted digraph with weights in the set of complex rational functions. A general procedure is proposed which allows for the reduction of G to a smalle…
