Dynamical Sampling in Graph Paley--Wiener Spaces
Iulia Martina Bulai, Carlos Cabrelli, Elena Cordero +2
We study dynamical sampling for graph signals using the spectral theory of the normalized graph Laplacian. Graph Paley-Wiener spaces GPW_w are defined as spectral subspaces associa…
Uniform Chebyshev approximations of functions satisfying a variation-type condition: reconstruction of time-varying signals on graphs
Davide Bianchi, Sandra Saliani, Dimitrios Vavitsas
We prove uniform approximation theorems for Chebyshev expansions of continuous functions of two variables. Under a variation-type condition on the square , a continuous f…
On Cannon cone types and vector-valued multiplicative functions for genus-two-surface-group
Sandra Saliani
We consider Cannon cone types for a surface group of genus , and we give algebraic criteria for establishing the cone type of a given cone and of all its sub-cones. We also re-p…
Free Group Representations from Vector-Valued Multiplicative Functions, II
M. Gabriella Kuhn, Sandra Saliani, Tim Steger
Let be a non-commutative free group on finitely many generators. In a previous work two of the authors have constructed the class of multiplicative representations of and p…
Linear independence of translates implies linear independence of affine Parseval frames on LCA groups
Sandra Saliani
Motivated by Bownik and Speegle's result on linear independence of wavelet Parseval frames, we consider affine systems (analogous to wavelet systems) defined on a second countable,…
-Linear Independence for the System of Integer Translates of a Square Integrable Function
Sandra Saliani
We prove that if the system of integer translates of a square integrable function is -linear independent then its periodization function is strictly positive almost everywh…
