Phase retrieval for nilpotent groups
Hartmut Führ, Vignon Oussa
We study the phase retrieval property for orbits of general irreducible representations of nilpotent groups, for the classes of simply connected connected Lie groups, and for finit…

Phase retrieval for affine groups over prime fields
David Bartusel, Hartmut Führ, Vignon Oussa
We study phase retrieval for group frames arising from permutation representations, focusing on the action of the affine group of a finite field. We investigate various versions of…

On R-duals of type III in Hilbert spaces
Hartmut Führ, Jahangir Cheshmavar, Ali Akbarnia
Following work by Casazza, Kutyniok and Lammers, and extensions by Stoeva and Christensen, we provide some novel characterizations of R-dual sequences of type III in Hilbert spaces…
