The Canonical Quantization in Terms of Quantum Group and Yang-Baxter Equation

In this paper it is shown that a quantum observable algebra, the Heisenberg-Weyl algebra, is just given as the Hopf algebraic dual to the classical observable algebra over classical phase space and the Plank constant is included in this scheme of quantization as a compatible parameter living in the quantum double theory.In this sense,the quantum Yang-Baxter equation naturally appears as a necessary condition to be satisfied by a canonical elements,the universal R-matrix,intertweening the quantum and classical observable algebras. As a byproduct,a new ``quantum group'' is obtained as the quantum double of the classical observable algebra
