DENSITY OF DILATES OF A SHIFT-INVARIANT SUBSPACE

[摘要] Sufficient conditions are given for the density of the dilates of the shift-invariant subspace S0(phi) generated by phi in L(p)(R(s)) with 1 less-than-or-equal-to p < infinity. The density of the dilates is also studied in the space C0(R(s)) of all continuous functions vanishing at infinity. (C) 1994 Academic Press, Inc.
