Extra-invariance of group actions
C. Cabrelli, C. A. Mosquera, V. Paternostro
Given discrete groups we characterize -invariant spaces that are also invariant under . This will be done in terms of subspaces that we define using an appro…
Dynamical Sampling for Shift-preserving Operators
A. Aguilera, C. Cabrelli, D. Carbajal +1
In this note, we solve the dynamical sampling problem for a class of shift-preserving operators acting on a finitely generated shift-invariant space . We find conditi…
Spaces invariant under unitary representations of discrete groups
Davide Barbieri, Eugenio Hernández, Victoria Paternostro
We investigate the structure of subspaces of a Hilbert space that are invariant under unitary representations of a discrete group. We work with square integrable representations, a…
Noncommutative Shift-Invariant Spaces
Davide Barbieri, Eugenio Hernández, Victoria Paternostro
The structure of subspaces of a Hilbert space that are invariant under unitary representations of a discrete group is related to a notion of Hilbert modules endowed with inner prod…
Extra Invariance of Shift-Invariant Spaces on LCA Groups
Magalí Anastasio, Carlos Cabrelli, Victoria Paternostro
Let G be an LCA group and K a closed subgroup of G. A closed subspace of L^2(G) is called K-invariant if it is invariant under translations by elements of K. Assume now that H is a…
