question

Hello Fellow-Surfers:

I have a question related to the article by Gilbert Strang
"Wavelets and Dilation Equations," SIAM, V. 31, #4, pp. 514-627,
December 1989.

On page 617, Strang says:


"For approximation with accuracy $h^p$ , the Fourier transform $ phi^{hat} $
must have zeros of order p at all points $ xi = 2pi n $ ....."

This statement occurs before "CONDITION A" in his paper. Can anyone
tell me where this statement comes from, i.e., from functional
analysis, approximation theory etc.

It is my understanding that a comprehension the origin of the above
statement is important in understanding CONDITION A.

I have many questions related to the paper but I would like to have
this answered first.

Thanks

Samir (chettri@nssdcs.gsfc.nasa.gov).
