Such stipulations usually occur at the beginningof the book, in the form of definitions, postulates, axioms, andso forth. Since stipulation of usage is characteristic of thesefields, it has been said that they are like games or have a"game structure."

Axiom (Dynamics). There is a distinguished quantum observable, the Hamiltonian H. Time evolution of states ψ(t)〉 ∈ H is given by the Schr ̈odingerequationi~ ddt ψ(t)〉 = Hψ(t)〉 (1.1)

Axiom (States). The state of a quantum mechanical system is given by a nonzero vector in a complex vector space H with Hermitian inner product 〈·, ·〉.

Axiom (Quantum observables). The observables of a quantum mechanical system are given by selfadjoint linear operators on H.
