Tight Wavelet Frames on Graphs via Isometric Group Embedding
Rigobert Fokam Souop, Laurent Bitjoka
The paper proposes constructing tight wavelet frames on graphs by embedding the graph isometrically into a Cayley graph of a finite abelian group, allowing exact Fourier analysis a…

Harmonic Analysis on Graphs via Isometric Group Embedding: A Canonical Fourier Transform, Shift, and Convolution for Network Signals
Rigobert Fokam Souop, Laurent Bitjoka
The paper proposes a new harmonic analysis framework for graph signals by embedding a graph isometrically into a Cayley graph of a finite abelian group, enabling a canonical Fourie…
