An Introduction to the Mathematical Aspects of Quantum Mechanics:
... Note that the Proposition 1.1 gives us the expected value of the momentum, free from Fourier transform under the price of the introduction of partial differentials. This gives us an important hint about the nature of quantum mechanical systems: We can define a Momentum Operator P̂ P̂ ψ = ...

The approach, as we will see when we discuss specific models, will be to define products of quantum fields, called normal products, with the property that operator ordering within the normal product is irrelevant and that the field equations are the normal produ ...

... Wick ordering in quantum mechanics [4], although not quite the same. I do not know if the identity (4) has any bearing on this subject. Two proofs of this identity will be discussed. The first is an application of the classical Lagrange inversion theorem [3], [7]. In fact, it will follow that the op ...
