This paper introduces a novel definition of GFT on directed graphs, and uses the singular values of the Laplacian to carry the notion of graph frequencies.
Examples of relevant problems that have been recently addressed using GSP tools include graph signal sampling [11]- [15], graphbased wavelet and Fourier ...
