Part of the book series: Operator Theory: Advances and Applications ((OT,volume 167))

Abstract

A unified account of a noncommutative operator trigonometry originated in 1966 by this author and its further developments and applications to date will be given within a format of a historical trace. Applications to wavelet and multiscale theories are included. A viewpoint toward possible future enlargement will be fostered.
