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…

The Restricted Isometry Property for Measurements from Group Orbits
Hartmut Führ, Timm Gilles
It is known that sparse recovery by measurements from random circulant matrices provides good recovery bounds. We generalize this to measurements that arise as a random orbit of a…
