Abstract

We consider a locally compact abelian group G with a uniform lattice L in G. In this paper necessary and sufficient condition under which shifts of a finite numbers of functions {φ1, φ2, · · · , φn} in L 2 (G) to be a Riesz family are investigated.

Keywords

, : Shift-invariant spaces, translation invariant spaces, LCA groups.
