Abstract
A complete description of the state of a dynamical system is provided by the wave function ψ ( r 1 , r 2 , ⋯) for the state. There are various ways of representing the wave function and hence the state. To discuss these representations let us choose a complete orthonormal set of functions u j ( r 1 , r 2 , ⋯); these satisfy the equations
