Coherent States and Wavelets, a Contemporary Panorama
2015In a first part, we review the general theory of coherent states (CS). Starting from the canonical CS introduced by Schrodinger in 1926 and rediscovered by Glauber, Klauder and Sudarshan in the 1960s, we proceed to the derivation of general CS from square integrable group representations and some of their generalizations: Perelomov CS, general square ...

On Some Quaternionic Coherent States and Wavelets
2015As a natural extension of the affine groups of the reals and the complexes, leading to one and two-dimensional wavelets, we look at the quaternionic affine group and its representations on both complex and quaternionic Hilbert spaces. We then study the problem of coherent states and wavelets built from these representations.
