Extra-invariance of group actions

By C. Cabrelli and others
Given discrete groups \(\Gamma \subset \Delta\) we characterize \((\Gamma,\sigma)\)-invariant spaces that are also invariant under \(\Delta\). This will be done in terms of subspaces that we define using an appropriate Zak transform and a particular partition of the underlying group. On the way, we obtain a new characterization of principal... Show more
