Wavelets were first introduced in the 1980’s. Similar to jpeg, they are used to digitize and compact data.

What You Should Know About Wavelets Professor Guido Weiss

Washington University – St. Louis

Wavelet theory is a rather broad mathematical subject that produces various ways of efficiently reproducing functions or signals. It can be used to study the properties of many function spaces and the operators that are defined on them. We begin with a discussion of the "first wavelet:" The Haar wavelet. We then will discuss how to extend this notion to higher dimensions.

Some applications of wavelets will be introduced.

The talk will be elementary and questions are encouraged.
