It differs in sign from Goldstein, Wikipedia and others. If, for a phase space function f(pi, qi) (that is, no explicit time dependence) [H, f] = 0, then f(pi, qi) is a constant of the motion, also called an integral of the motion. In fact, the Poisson bracket can be defined for any ...

If f and g are two constants of the motion (i.e., they both have zero Poisson brackets with the Hamiltonian), then the Poisson bracket [ f, g] is also a constant of the motion. Of course, it could be trivial, like [ p, q] = 1 or it could be a function of the original variables. But sometimes it’s a new constant of ...
