Explicit constructions and properties of generalized shift-invariant systems in
Ole Christensen, Marzieh Hasannasab, Jakob Lemvig
Generalized shift-invariant (GSI) systems, originally introduced by Hernández, Labate & Weiss and Ron & Shen, provide a common frame work for analysis of Gabor systems, wavelet sys…

On partition of unities generated by entire functions and Gabor frames in $\ltrd$ and $\ell^2(\mzd)$
Ole Christensen, Hong Oh Kim, Rae Young Kim
We characterize the entire functions of variables, for which the $\mzd$-translates of satisfy the partition of unity for some $N\in \mn.$ In contra…

On the Gabor frame set for compactly supported continuous functions
Ole Christensen, Hong Oh Kim, Rae Young Kim
We identify a class of continuous compactly supported functions for which the known part of the Gabor frame set can be extended. At least for functions with support on an interval…
