Wick ordering for coherent state quantization in 1+1 de Sitter space

Abstract

We show that the coherent state quantization of massive particles in 1+1 de Sitter space exhibits an ordering property: There exist some classical observables $A$ and $A^{\ast }$ such that $O_{A^{\ast p}}{O}_{A^q}=O_{A^{\ast p}{A}^q}$ $p,q\in \mathbb{Z}$, where $O_A$ is the quantum observable corresponding to the classical observable $A$.
