摘要: The HAP for the continuous wavelet transform is studied when the integral intervals of two variables are both finite. If the pointwise HAP holds, the function to be reconstructed must be 0 has been proved, when ψ1=ψ2. This is very different from infinite interval. For ψ1≠ψ2, some necessary conditions is given.
