## Main Question or Discussion Point

Hi , I can't understand the general formula for weyl ordering of the hamiltonian . It is written in Srednicki field theory book in page 68 . Can someone explain how to derive this formula ?

In case of a curved manifold with a free particle moving on that manifold one reasonable idea is to use the Laplace-Beltrami operator as kinetic energy; this results in a unique operator ordering.

Perhaps Srednicki explains something like that ...

O(q

But difficult questions like operator ordering are a reason that people turned away from Langrangian formulation and were led instead to path integrals.
