Translation preserving operators on locally compact abelian groups
M. Mortazavizadeh, R. Raisi Tousi
We study translation preserving operators, that is operators commuting with translations by a closed subgroup of a locally compact abelian group. We show that there is a one to one…
On the semi-regular frames of translates
F. Valizadeh, H. Rahimi, R. A. Kamyabi Gol +1
In this note, we fix a real invertible matrix and consider as an index set. For , let $Φ^{\mathcal{A}}_{…
N strongly quasi invariant measure on double coset
Fatemeh Fahimian, Rajab Ali Kamyabi Gol, Fatemeh Esmaeelzadeh
Let G be a locally compact group, H and K be two closed sub-groups of G, and N be the normalizer group of K in G. In this paper, the existence and properties of a rho-function for…
Finite Synchrosqueezing Transform Based On The STFT
Mozhgan Mohammadpour, Bastiaan Kleijn, Rajab Ali Kamyabi Gol
The finite STFT Synchrosqueezing transform is a time-frequency analysis method that can decompose finite complex signals into time-varying oscillatory components. This representati…
Gabor Tight Fusion Frames: Construction and Applications in Signal Retrieval Modulo Phase
Mozhgan Mohammadpour, Brian Tuomanen, Rajab Ali Kamyabi Gol
Hilbert space fusion frames are a natural extension of Hilbert space frames, extending the notion from a set of vectors in a Hilbert space to a set of subspaces of a Hilbert space…
