Representing topological full groups in Steinberg algebras and C*-algebras
Becky Armstrong, Lisa Orloff Clark, Mahya Ghandehari +2
We study the natural representation of the topological full group of an ample Hausdorff groupoid in the groupoid's complex Steinberg algebra and in its full and reduced C*-algebras…
Constructing non-AMNM weighted convolution algebras for every semilattice of infinite breadth
Yemon Choi, Mahya Ghandehari, Hung Le Pham
The AMNM property for commutative Banach algebras is a form of Ulam stability for multiplicative linear functionals. We show that on any semilattice of infinite breadth, one may co…
Signal processing on large networks with group symmetries
Kathryn Beck, Mahya Ghandehari, Jeannette Janssen +1
Current methods of graph signal processing rely heavily on the specific structure of the underlying network: the shift operator and the graph Fourier transform are both derived dir…
Robust Recovery of Robinson Property in -Graphons: A Cut-Norm Approach
Mahya Ghandehari, Teddy Mishura
This paper investigates the Robinson graphon completion/recovery problem within the class of -graphons, focusing on the range . A graphon is Robinson if it…
Frames for signal processing on Cayley graphs
Kathryn Beck, Mahya Ghandehari, Skyler Hudson +1
The spectral decomposition of graph adjacency matrices is an essential ingredient in the design of graph signal processing (GSP) techniques. When the adjacency matrix has multi-dim…
