Science China Mathematics 2012年 第7期55卷 1395-1401页
作者: ZHANGQingYue SUNWenChang Department0}MathematicsandLPMC。NankaiUniversity}Tianjin300071 China
In this paper, we give a characterization of shift-invariant subspaces which are also invariant under additional non-integer translations. Both principal and finitely generated shift-invariant subspaces are studied. O... 详细信息
