Webgraph signal processing is based on the graph Laplacian. In our development the graph A is allowed to have complex edge weights and can be directed. Using the canonical definition of the decimator in (9) and eigenvector-shift operator Ωin (45), the DU operator can be written as a sum of powers of Ω. That is, DTD 1 M M-1 k 0 Ωk.
