Sampling, Filtering and Sparse Approximations on Combinatorial Graphs
Isaac Z. Pesenson, Meyer Z. Pesenson
In this paper we address sampling and approximation of functions on combinatorial graphs. We develop filtering on graphs by using Schrödinger's group of operators generated by comb…

Variational Splines and Paley--Wiener Spaces on Combinatorial Graphs
Isaac Pesenson
Notions of interpolating variational splines and Paley-Wiener spaces are introduced on a combinatorial graph G. Both of these definitions explore existence of a combinatorial Lapla…
