ABSTRACT
Wavelets were introduced by J. Morlet, a French petroleum engineer at ELF-Aquitaire, in connection with the study of seismic traces. The Mathematical fundations were given in a paper by A. Grossmann and J. Morlet [61]. The harmonic analyst Y. Meyer and many other Mathematician become aware of this theory and they recognized many classical results inside it (see [64] [81] [87] [96]).
