On amenability constants of Fourier algebras: new bounds and new examples
Yemon Choi, Mahya Ghandehari
Let be a locally compact group. If is finite then the amenability constant of its Fourier algebra, denoted by , admits an explicit formula [Johnson, J…
Consistent sampling of Paley-Wiener functions on graphons
Hartmut Führ, Mahya Ghandehari
We study sampling methods for Paley-Wiener functions on graphons, thereby adapting and generalizing methods initially developed for graphs to the graphon setting. We then derive co…
On the restriction maps of the Fourier and Fourier-Stieltjes algebras over locally compact groupoids
Joseph DeGaetani, Mahya Ghandehari
The Fourier and Fourier-Stieltjes algebras over locally compact groupoids have been defined in a way that parallels their construction for groups. In this article, we extend the re…
Unified Fourier transform on graphs sampled from stochastic block models
Mahya Ghandehari, Jeannette Janssen, Silo Murphy
Recently, an approach to graph signal processing based on graphons was proposed. Here we show how such a graphon-driven approach to the Fourier transform can be used on graphs samp…
The Large Deviation Principle for -random spectral measures
Mahya Ghandehari, Georgi S. Medvedev
The -random graphs provide a flexible framework for modeling large random networks. Using the Large Deviation Principle (LDP) for -random graphs from [9], we prove the LDP fo…
Wavelet characterizations of the Sobolev wavefront set: bandlimited wavelets and compactly supported wavelets
Hartmut Führ, Mahya Ghandehari
We consider the problem of characterizing the Sobolev wavefront set of a tempered distribution in terms of its continuous wavelet transform, with…
