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 … WebApr 16, 2014 · The general magnetization response to this CPMG sequence was simulated using the rotation operator algorithm (ROA) 5.The ROA represents the direct algorithmic conversion of the Bloch equation 6 into …
