Abstract:We present the geometric quantization of the standard Podles sphere by using a multiplicative real polarization of the symplectic groupoid. We introduce the concept of multiplicative integrability of the modular function as one key point of the construction.
“…As mentioned in the introduction we will look for a possibly singular multiplicative lagrangian distribution such that the modular 1-cocycle descends to the leaf groupoid. It is natural to seek for a modular multiplicative integrable system, as we considered in [3], i.e. a maximal set F of functions in involution, almost everywhere independent, generating the modular cocycle c V (3.5) and such that the space of level sets G F (S 2 θ ) inherits the groupoid structure.…”
We show an example of quantization of a singular Poisson structure on the sphere sharing the same C * -algebra quantization as the Podleś one but with different quasi invariant probability measure and the quantization of the modular automorphism.
