Title:  Wavelets Made Easy (Almost)

Abstract:

 The purpose of this talk is to present the topic of Wavelets
at a level accessible to a first year graduate student. We
begin the talk with a discussion of why Wavelets are important
(i.e applications) and where they fit in the grand scheme of
mathematics. While most of the analysis aspects of the
subject are complicated by computations and shifts of Fourier
Transforms on the Hilbert Space L^2(R), we will derive Ingrid
Daubechies moment equations for D4 and D6 by asking (and then
answering) easy-to-understand questions about the column
space of a matrix.
In particular, we will explain the origin of the equation

C_1 - 2C_2 + 3C_3 = 0 for D4.
