The closedness of shift invariant subspaces in [Formula: see text]
In this paper, we consider the closedness of shift invariant subspaces in [Formula: see text] . We first define the shift invariant subspaces generated by the shifts of finite functions in [Formula: see text] . Then we give some necessary and sufficient conditions for the shift invariant subspaces i...
