Pseudo-Spin-Coherent States,w consider analogue setting when the sphere is replace by the 2-pseudo-sphere i.e. the Euclidean metric in ?. is replaced by the Minkowski metric and the group .(3) by the symmetry group .(2,1). The main big difference with the Euclidean case is that in the Minkowski case the pseudo-sphere in non co

Bosonic Coherent States,spin and have symmetric wave functions; fermions are quantum particle with half-integer spin and are represented with anti-symmetric wave functions. The functional setting is given by symmetric or anti-symmetric tensor product of Hilbert spaces. We describe these spaces and transformations between t

Weyl Quantization and Coherent States,s and applications to propagation of observables..We show that Wick quantization is a natural bridge between Weyl quantization and coherent states. Applications are given of the semi-classical limit after introducing an efficient modern tool: semi-classical measures..We illustrate the general result

In particular we get the explicit form of the Weyl symbols of the metaplectic transformations. These formulas are generalizations of the Mehler
