Subspace dual and orthogonal frames by action of an abelian group

In this article, we discuss subspace duals of a frame of translates by an action of a closed abelian subgroup Γ of a locally compact group G . These subspace duals are not required to lie in the space generated by the frame. We characterise translation-generated subspace duals of a frame/Riesz basis...
