Abstract
For a class of continuously differentiable function Ï satisfying certain decay conditions, it is shown that if the maximum gap δ:=supiâ¡(xi+1âxi) between the consecutive sample points is smaller than a certain number B0, then any fâV(Ï) can be reconstructed uniquely and stably. As a consequence of this result, it is shown that if δ<1, then {xi:iâZ} is a stable set of sampling for V(Ï) with respect to the weight {wi:iâZ}, where wi=(xi+1âxiâ1)/2 and Ï is the scaling function associated with Meyer wavelet. Further, the maximum gap condition δ<1 is sharp.
