    "abstract": "The Dirac method is used to analyze the classical and quantum dynamics of a\nparticle constrained on a circle. The method of Lagrange multipliers is\nscrutinized, in particular in relation to the quantization procedure. Ordering\nproblems are tackled and solved by requiring the hermiticity of some operators.\nThe presence of an additional term in the quantum Hamiltonian is discussed.",
