Abstract

As a sequel to the previous chapter, it is of interest to seek another subspace M of L 2(ℂ n such that the product of two Daubechies operators with symbols in M is a Daubechies operator with symbol H in M. We prove in this chapter that M can be taken to be the subspace of L 2(ℂ n spanned by Gaussian functions. Furthermore, an explicit expression for H is given.
