"Signal Sampling and Interpolation on Community Graphs"

Pesenson, Isaac

We establish discrete Plancherel-Polya-type inequalities(or Marcinkiewicz- Zigmund-type or frame inequalities) for signals whose gradients satisfy a Bernstein- type inequality. These results enable the development of a sampling theory for signals on undirected weighted finite or infinite graphs. Although our approach is applicable to general graphs it’s especially well suited for finite and infinite graphs with multiple clusters. Such graphs are known as community graphs and they find many important applications in materials science, engineering, computer science, economics, biology, and social studies.
