shift-invariant spaces%difference operators%linearly independent shifts%generator
Shifts-invariant spaces in L1(R) are investigated. First,based on a study of the system of linearly difference operators,the method of constructing generators with linearly independent shifts is provided. Then the characterizations of the closed shift-invariant subspaces in L1(R) are given in terms of such generators and the local basis of shift-invariant subspaces.
