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…
