A discussion of these relations is the topic of my paper: The global structure of the set {Q(M, K)} of quantizations of the kinematics in a Hilbert space H is connected with a nonlinear representation of a matrix group G which leads also to a quantization of other observables through nonlinear operators.	cache/ap-1201.pdf	txt/ap-1201.txt
