“…Developing methods to identify suitable bases or frames for low-spectrum Paley-Wiener spaces is an important area of research in graph signal processing, particularly in the case of clustered but otherwise general graphs (e.g, [32]). Analogues of Slepian-type eigenfunctions on graphs [8,9] are a relatively new aspect of this.…”

“…Note, that all the inequalities in this Theorem are some sort of generalized Poincaré-type inequality since they contain estimates of a function through its gradient. Using these estimates the next statement about a Plancherel-Polya-type (or Marcinkiewicz-Zygmund, or frame) inequalities can be proved (see [17]). For every f ∈ E ω (G) with ω satisfying…”

“…Graph signal processing is a cutting-edge research field for the study of graph signals in which mathematical processing tools as filtering, compression, noise removal, sampling, or decomposition methods are investigated [6,11,[22][23][24]26,33,35]. Graph structures appear naturally in a multitude of modern applications, as in social net- works, traffic maps or biological networks.…”
