Quantization and Coherent States on the 2-TorusThe two dimensional torus . is a very simple symplectic space. Nevertheless it gives non trivial examples of chaotic dynamical systems. These systems can be quantized in a natural way. We shall study some dynamical and spectral properties for them.

Then applying it to a Schwartz class state of arbitrary profile we get a set of generalized coherent states.

This problem is called the semi-classical limit problem. In this chapter we discuss properti
