Most applications of Harmonic Analysis to analyzing a given set of points fx jgn j=1 ˆR N involve de ning a graph and constructing some type of discrete analog of the Laplace operator. However, there is a rather direct WebNov 28, 2024 · We introduce a novel harmonic analysis for functions defined on the vertices of a strongly connected directed graph of which the random walk operator is the cornerstone. As a first step, we consider the set of eigenvectors of the random walk operator as a non-orthogonal Fourier-type basis for functions over directed graphs. We found a …
