On the Isomorphism Problem of Cayley Graphs of Graph Products [PDF]

arXiv
We investigate Cayley graphs of graph products by showing that graph products with vertex groups that have isomorphic Cayley graphs yield isomorphic Cayley graphs.

Graph Signal Processing: Modulation, Convolution, and Sampling [PDF]

arXiv, 2019
To analyze data supported by arbitrary graphs G, DSP has been extended to Graph Signal Processing (GSP) by redefining traditional DSP concepts like shift, filtering, and Fourier transform among others. This paper revisits modulation, convolution, and sampling of graph signals as appropriate natural extensions of the corresponding DSP concepts.

Sampling Theory for Graph Signals on Product Graphs [PDF]

arXiv, 2018
In this paper, we extend the sampling theory on graphs by constructing a framework that exploits the structure in product graphs for efficient sampling and recovery of bandlimited graph signals that lie on them. Product graphs are graphs that are composed from smaller graph atoms; we motivate how this model is a flexible and useful way to model richer ...

Demystification of Readiness, Security, and Technological Enhancements in the Adoption of a Cashless Economy

Economies
The adoption of a cashless economy was accelerated globally by the devastating impact of the COVID-19 pandemic. Brunei Darussalam was not excluded from this trend, as pandemic-related restrictions were implemented to ensure the safety of its population ...

Theoretical Insights into Line Graph Transformation on Graph Learning [PDF]

arXiv
Line graph transformation has been widely studied in graph theory, where each node in a line graph corresponds to an edge in the original graph. This has inspired a series of graph neural networks (GNNs) applied to transformed line graphs, which have proven effective in various graph representation learning tasks.
